Mastering frequently asked questions

Here is a short video documenting the studio, please note this video is 8 years old. There has been many upgrades to acoustics, software and equipment since the video was made.

Condensed, useful and informative online mastering answers

Please send 24 bit (32 bit float also ok) music mixes, at your project sample rate, no limiters or clipping of the output. Precise headroom below 0dBFS is not critical as long as there is no clipping, (squaring off of peaks in audio).

You can leave compression on if just for tone or gentle dynamic enhancement. If used for only perceived volume increase please remove.

Check through actual bounced music file and check for clicks. (especially in vocals, ends of phrases, synth envelopes), abrupt file starts (cut off instruments) –  Ensure enough time at end to allow natural decays.

Turnaround approx 1-2 days for 1 Track, 3-4 days for an EP and 1 week for an album.
