The battle of concepts or harmony in their co-existence?


Since the invention of digital technology marked by arrival of Pro Tools and similar computer-based systems, both musicians and producers have engaged in discussions which of the two concepts of producing audio recordings is better? Can these two concepts co-exist, or be combined somehow to complement each other, or should one opt for choosing just one or the other and why? Lastly, what are the advantages of producing music digitally versus via analog means? While I'm not going to give you clear answers here, I will provide you with an opportunity to hear and listen what is my take on all this. As demonstrated by my YOUTUBE music channel, you can easily make up your own mind about the benefits of analog tube and tape mixing techniques I'm fond of using.

To reiterate my point, the best professionals in today's audio music productions have found a way to combine both analog and digital processes for the best, most consistent results. That means, they found a way to use what are the best aspects of each concept and found a perfect marriage of the two, depending on the production needs they or their clients have. Now, as there are many roads that lead to Rome, there are many different ways of working with audio tracks that help achieve similar results. My view points and suggestions below come exclusively from my 20+ years of experience as both performing and recording artist as well as tracking, mixing, and mastering engineer. By no means, I claim this is the best way. Just one of many, which I have found to work well - at least for my needs.


For one, every source out there has always been recorded via analog means, because sound has to be captured via microphone and preamplifier, which both are analog by the nature of their design. At one point, Neumann started manufacturing digital microphones for a little while, but that trend didn't catch on. When recording into a computer or DAW (digital audio workstation), the next step in the signal chain hierarchy is A/D (aka analog to digital) converter, which translates the analog signal captured by microphones diaphragm and amplified by preamplifier into digital language of zeros and ones. Once you have the track/s inside your DAW, you can and often do manipulate them and/or mix them via digital means. So, it is not possible to separate the two processes from each other once a hard drive is used to store your precious audio tracks for future manipulation. Therefore, they must co-exist.

On one hand side then we have the convenience of today's DIGITAL TECHNOLOGY, with all its positives such as all-in-one digital audio workflow where one can produce entire CD using computer or specialized computer-like digital audio workstation, where you can not only record and edit all tracks, but also mix and master them using so called virtual plug-ins, which for the most part emulate real analog gear of the past, such as equalizers, compressors, delays, reverbs, etc. We call this concept MIXING IN-THE-BOX and it has became a very popular way for young and upcoming artists who are on the budget and can't afford paying for real professional studio time or renting of precious analog equipment needed to mix their music in any other way.

On the other hand side we have the option of using either ANALOG MIXER or ANALOG CONSOLE along with a TAPE RECORDER, where mixing actively or passively is done via analog means or via a custom designed SUMMING BOX. This concepts often renders nicely warm and full bass-response, and naturally tape compressed and saturated tracks, which resemble all that sound of recordings from the time when recording via analog means was the only option. However, this concept also requires a good amount of very costly analog out-board equipment as well as expensive and hard to find analog reel to reel tape, not speaking of the climate-controlled storage space needed to preserve all those analog reels and some technical skills to keep all those machines in fine shape, both sonically and mechanically. From this perspective, mixing analog is the much more difficult and time consuming endeavour when compared to digital mixing.

In the examples provided shortly on this website you will be able to compare how both digital and analog mixes of the same material sound when you A/B them in a listening test. For real audiophiles, I will provide 16bit/44.1kHz tracks of these excepts, where the differences will be a bit more noticeable then in the compressed MP3s below. There will be close to no processing after each mix was produced, except for bringing the levels up close to 0db on a digital scale (simply by raising their volume in post-production). You will notice that the analog mixes will sound louder and fuller than their digital counterparts. That's because of the analog processing and all that gear which was used during that process… Ideally, you would want to bring all the different mixes into a DAW of your choice (Pro-Tools, Nuendo, Sonar, Cubase, Logic, etc.) and match the volumes of them all using your ears for the most accurate and fair listening comparison of them all. However, it is my hope that even with the MP3s 320kbps and VBR at our
Audio Samples section, the differences between various mixing concepts will easily be recognizable even to a less experienced listener.

I have spent over 20 years researching and collecting equipment which I find ideal for my needs as an audio engineer, both for mixing and mastering. While my budget is not limitless, I've been pretty lucky to get my hands on some of the best analog gear ever produced, which makes a noticeable difference in the way my music productions sound.


On average, depending on the quality of the tracking job and if it is an inside job (done by me or someone I know well) or outside job (tracked anywhere around the Globe without my participation), it takes about 120 hours to mix a 60+ minute long music CD album via analog means. That's a lot of night shifts, folks! This assumes that all the tracks have already been edited accordingly, proper takes have been selected and no further music recording or modification needs to take place. This is the preferred way when working globally, because the mixer and the client do not have to be present in one room and the mixer has the freedom to work his magic at his own pace and time.

1. the most important stage is the very first one, called tracking, which includes selection and placement of microphones and preamplifiers and determination of proper instrument spaces to be used (large tracking room vs. ISO booth). As a rule of thumb, always pick the best mic/preamp combo you can find, and don't be afraid of recording each source with more than one mic (if resources allow). During the mixing process you can make a decision, which of the mics selected sounds the best for your needs or sometimes combine them to find that "right" balanced sound. Try to match a good preamp with the type of instrument and microphone you are recording with. For example, when recording drums, the best sounding preamps are vintage Langevin AM16, which cost only around $350-400 each unracked on ebay. They handle drums' transients incredibly well and are known to be among the best sounding for drums, period. Given their price range, they are also very affordable.

2. the room selection - when recording in separation, or mic-ing instruments closely, the room sound may not be as important, but when recording one group live in one place, or wanting a big drum sound, this is crucial. Sound bleeding is one of the biggest nightmares of mixers, as it is the hardest one to eliminate during mixing processes. Too live of a room and no matter how good your mics and their placement are, your mixer will have a heck of a time trying to make it sound just half-descent. That's why many studios feature padding on the walls, uneven angles, special flooring - to help eliminate reflections and bleeding.

3. analog to digital conversion (so called A/D stage) - pick the best converters you possibly can get your hands on. Most studios will use custom build-ones or build by manufacturers who are known to be among the best. In our home studio, we use British PRISM ADA8-XR exclusively (we have 8 channels of analog I/O and 8 channels of digital I/O), but our other converters are also great, such as TC Electronic's M6000 AD/DA cards (we have six channels total) or Db Technologies aka Dan Lavry Blue or Gold series or older Genex products, which are on par sonically with the Prism line of products. We avoid using Pro-Tools HD 192 conversion at all costs as it sounds a bit dull when compared with the above-mentioned converters, but when tracking 30+ instruments, even some of those channel available can become useful.

4. stable clock - this is important during both tracking and mixing stages. We are pretty happy with PRISM's own clock, which everything else is clocked to in our studio. Some studios prefer custom made clocks. It's all matter of cost and convenience of course. Stable clock is a very important feature to have however!

5. stable DAW - our workflow speed is very important. That's why we use Pro-Tools HD3 system with Apple's Mac Pro computer, which is more then sufficient running multiple plug-ins and many tracks at once. Good thing that other World-class manufacturers were able to meet Pro-Tools system protocol and that we can plug our PRISM directly to HD Core card with no issues. This makes a big difference.

6. while it is a standard today at most studios to record digitally, the best studios will still record up to 24 tracks at once to a two-inch tape recorder before the audio is captured digitally via A/D conversion. This is by far the best quality sound one can achieve, however at a very high cost and also most time-consuming and cumbersome to deal with when making music on the fly. When running tape at 30IPS (inch-per-second), the tape has to be changed every 16 minutes, or you need multiple machines synchronized together to double this limit before a change of tape can happen. Most studios will record at 15IPS, which gives you about 33 minutes on one professional tape. This is better. Now, a cost of 2-inch GP9 tape (to fit all 24-tracks at once) is around $350 per tape on todays market as these are no longer made! Say you need 5-6 to make an album… And being a pro-studio which records onto tape exclusively - well, imagine storing all those tapes for future use or recall... That's why often, these tapes are rented out by clients and reused many times. GP9 for example, our most favorite and the best sounding, can be reused 30-50x - depending on how well the recorder is calibrated and what type of heads are used (hint: butterfly heads are the best and also most costly).

So, a compromise is to record straight into DAW via super high quality A/D conversion and use the tape at a later stage during mixing and/or mastering, which is what we have been doing for some time now at sonicADventures. That way you have close to an unlimited amount of space to record onto (limited only by the size of your hard drive/s) and you by-pass the costly process of using analog tape during tracking, which slows down the workflow noticeably. Lastly, there is the issue of tape noise - so unless you get your levels peaking close to the very top, this can become an issue during the mixing stage - too much noise from tape when levels are boosted to today's standards.

7. once you pre-mix your tracks inside your DAW and pan each instrument where it needs to be, adjust delay or reverb accordingly to get some 3D spacing, add some plug-ins such as EQ or compression to help your tracks stand out or match better your overall idea of the sound, you are ready to mix. Some examples below (often early mixes) will be mixed inside our protools HD system this way. In my experience, it is a good practise to try a few mixes via DAW and then A/B them against some CD recordings of similar style of music and instrumentation to get a direct feedback. This is usually an eye opener and gives you rather cruel perspective on the sound of your DAW mix. That's because most if not all of your favorite CD albums out there were mixed via analog means and that sound can not be reproduced with plugins, unless it is captured onto a tape at first place using all that expensive outboard gear. I prefer recording everything raw however, with no outboard EQ or compression applied, since once you record the signal, it is captured that way once for all and can't be changed without making some serious compromises later. Of course, if your studio has been running for a longer time and you have already figured out that favorite drum or piano sound by knowing what type of outboard gear to add to the chain and what combo of mics/preamps to use, by all means go for it! It will only simplify and speed up the mixing stage at a later time.

8. after you have worked hard on your digital mix within your DAW, you will be left with some mixed emotions. You know that you did your best utilizing your plugins and the way you've imagined the sound to work in a standard listening environment, yet it doesn't quite sound on par with your favorite albums - often not even close… Have you noticed how the market in the last ten years or so have been gradually saturated with so called SUMMING BOXes? What are those about and do they improve your mix? The answer for the most part is YES, although going deeper it really depends on many aspects and therefore it is hard to generalize. Many people/artist will opt to hire a professional mastering engineer to "fix" their "in-the-box" digital mixes, bring up the levels to today's standard, and help warm-up the overall sound. Mastering engineers will have a very hard time processing this type of DAW mix and a lot of their skill and time will need to go into making the music sound half-descent. Some will ask for the music to be remixed and even recommend a mixing engineer who they know is very good. This all can be avoided with proper mixing stage at first place!

SUMMING BOX, similar to an analog mixer, gives you an option of running all your mixed tracks from your DAW back to the analog word (via D/A conversion) and have them mixed/summed via analog means - just like in the past before digital technology was available. Most summing boxes are either passive or active. Passive ones have the greatest frequency response (ours custom made goes 2Hz - 500kHz with no noticeable loss in any frequency spectra), but are often unbalanced and require a high quality preamplifier to amplify the sound of the passive mix. Active ones usually don't require additional amplification and are often fully balanced for better noise-specs and rejection. Most are however limited in their frequency response and don't achieve same specifications as some hand made or manufactured passive units (think Folcrom for example).

Most big studios will however prefer using their large ANALOG CONSOLE or ANALOG BOARD/MIXER, which already includes great summing section, plus usually EQ on each channel and some bus compressor on the main bus as well. Many engineers prefer mixing on these large boards because of the way they sound. Think big NEVE or SSL boards, which cost around $120k - 200k each (depending on size and amount of channels). With a SUMMING BOX, you can bypass using a dedicated mixer and still engaged variety of outboard gear (when available) to mix at a very high level. Often, the variety of the outboard gear is what helps individual instruments stand out in the mix.

To wrap this one up, I have read online that some of the best large analog consoles of the past utilized a passive summing box on their main bus, which then used a built-in preamp to amplify the sound of the final mix before coming back to the console for listening. Passive summing box's advantage is almost limitless amount of headroom and no distortion, where analog sources are mixed as voltages and bottle-neck issues associated with some active summing boxes or even summing units on large consoles are simply non-existent. This is in part, why digital mixing doesn't sound that good - because of the bottleneck issue associated with 24bit files. Imagine running 24 tracks of 24bit material within protools into a two channel stereo bus, which works at the same resolution or at 32bit one at best. Bottle-neck comes to mind and some information from these tracks will be dismissed by the digital mix bus because of this. It is possible that the newly designed 64-bit workstations will improve upon this known limitation, but the bottle-neck issue will still be present, albeit on a much smaller scale.

9. Once all your digital tracks, already pre-mixed, are going to an analog mixer or a summing box (via D/A conversion), you are ready to mix via analog means. The question now is, on what type of master recorder do you print your final mix onto?

Stage 1:
well, you can go back to your DAW, which is the fastest and easiest to do at this stage. This is usually a good way to compare how your original digital mix sounds like vs. your newly created analog mix. Usually, this is a first eye opener what analog mixing can do to the sound of your music or production, but sometimes the difference is subtle - depending on the type of music you work with and your skill set and amount of outboard gear, of course.

Stage 2:
while going out your DAW via D/A stage, use as much outboard gear as you can get your hands on to EQ, compress, or manipulate your track's individual sound and then use the output of your outboard gear to go into your summing box or analog mixer. Record back to your DAW for easy comparison and A/B test to hear the difference. Most mixes come alive, especially if you used high-end outboard gear, which is either tube based or solid state class A or A/B design. Vintage Neve, Studer, Neumann, Pultec, Lang, Langevin, Telefunken, Manley, Tube-Tech, Universal Audio, LA2A, etc come to mind here. Some are great for some instruments, others work great on most sources. There is never one unit to do it all however - sorry.

Stage 3:
same as stage two, except you record your mix straight onto a reel to reel master recorder. Swiss Studer tape decks are known to be among the best in the World. We use their A80 customized model with 1/2 inch GP9 or Ampex 499 GOLD tapes and custom butterfly heads exclusively for best results. The mixes going through our tape machine sound simply amazing! You then capture the sound of the tape playback into your DAW, at which point it is close to being ready to be send off to your mastering engineer of choice. The engineer then will translate your high end mixes (often 24bit/96kHz) to a standard CD format of 16bit/44.1kHz using specialized digital outboard gear (plug-ins don't work very well for this type of work and we've tried them all) and make sure that it is ready for a manufacturing plant to be burned onto commercially ready CD media. Our favorite processor for this type of conversion is Db Technology/Lavry 3000S unit as well as our Prism's ADA8-XRs own's dither curves and down-sampling hardware options.

10. When your mastering engineer received a properly mixed record using analog mixing technique (either via tape or not), he or she will have a big smile on their face. They no longer will have to fight for your mix to sound warm and dynamic and all they have to worry about is the levels of all tracks in comparison and overall balance when using it for radio broadcast or online streaming. When mix is recorded to a tape, mastering should be done via digital means exclusively to preserve the original sound of the tape and avoid additional AD/DA conversion, which degrades the original sound of the mix noticeably. More on this in my next section, called


As with all A/B tests, just like when listening during mixing or mastering stage, it is highly recommended that you use the highest quality listening equipment you can get your hands on. For example, owning an outstanding set of headphones if you are a professional musician who not only performs but likes to listen to a lot of quality uncompressed music, is a must. My recommendation goes to either
Stax 009 with a dedicated balanced amp (made in Japan) or Sennheiser HD800 set of headphones. If spending $6,000+ or even $1,500 on set of headphones is too much for your taste, good set of home monitors or Hi-Fi audio playback equipment will most likely suffice. Generally, your laptop speakers are not suitable at all to hear any difference in any A/B listening comparisons because of their very limited frequency response and tiny sound they usually produce.
