I'm a mixing engineer & producer with over 15 years of experience mixing audio and I come from a musician's background (over 25 years trumpet, BA in Music from Columbia University).
For just $5.00 I'll perform a basic mix on one entire song-- no track limits. This would just include EQing and compression and would not include FX or automation. It'd be enough to give a nice clean sound to your mix. I will deliver this in 24 hours or less. Please see the upper tier packages for further fine-tuning of your track.
Alternatively, for just $5.00 I'll master your already mixed track to make it radio/soundcloud/bandcamp, etc. ready.
What I'd need from you:
At least 16-bit (ideally 24-bit) Wave or AIFF files. MP3s aren't ideal, but I'll take them also (these should be at 320kbps).
If submitting for a mix, please submit separate stems for each track
If submitting for mastering, please submit your bounced stereo mix (ideally a minimum of 24-bit)
Please make sure all tracks have some headroom and are not clipping (ideally tracks should max out around -6dB)
