• It almost goes without saying - Nearly any digital PCM format - preferably 24- bit .WAV, at any sample rate up to 192kHz.
Should be in the "FAQ" but this seemed a good place -- What's the ideal digital format? Typically, I'm going to have to say that 24-bit PCM data (.wav, .aiff, etc.) at whatever sample rate you're working in (44.1 or higher preferred), with no limiting or excessive compression on the main buss and *some* amount of "natural" headroom. Could be 1dB, could be 3dB, 6, 10, 20 -- It doesn't really matter. Typical? Maybe around 5 or 6dB of clear headroom (and on a related note, I'd hope that you had at least that much if not twice as much on each individual track when you were recording). It's almost difficult to have "too much" headroom -- It's very easy to have too little. Better to have WAY too much than not enough.

  • We are no longer accepting 1/4” & 1/2” analog tape at 15 or 30ips. End of an Era - We’ve sold off our beloved MCI JH-100C deck. It’s now at a studio in New York that loves it as their main 2-track deck.

* NOTE: MP3, cassette, MiniDisc would be considered “last resort” formats - Only use if the only possible version of a project isn’t available in a standard higher resolution format.  *IF* the only version is one of these formats, do NOT alter it - Don’t make PCM versions of existing MP3’s, don’t make DSD versions of existing PCM data or CD’s, etc.  Changing the format will NOT increase the quality of the source material.  In some cases, it can damage it substantially.

** Alesis offers the CD-24 ISO BUILDER (FREE!!!) that will convert a collection of  24-bit .AIF files into an .ISO image file.  After the ISO file is created, use your CD writer software to “Create CD from Image File” (check your software’s instructions) and PRESTO!  You now have a CD-24 readable by MasterLink OR your PC’s CD/DVD drive!  If you don’t have a MasterLink, just check to make sure that your CD drive reads the AIF files before sending out.


If submitting stems (hourly rates apply), it’s preferred to have songs grouped together on the same discs whenever possible.

*Do NOT send project files or proprietary file types!  ProTools projects, SDII’s, NPR’s, etc. are not acceptable.  If sending digital mixdown files, they must be PCM data (WAV, AIFF, etc.).  If in doubt, please contact first!
