Mixing and Mastering AIMove between sample rates and bit depths cleanly.
Change a file's sample rate or bit depth with a proper band-limited resampler, rather than the quick conversion some exporters do on the way out.
It matters because a careless rate conversion adds aliasing, and a careless bit-depth reduction adds quantisation noise. Both are permanent once they are in the file.
Key points
- Convert between 44.1, 48, 88.2, 96 kHz and beyond without aliasing.
- Reduce bit depth for delivery, or raise it for further processing.
- 44.1 kHz is the CD and streaming standard; 48 kHz is standard for video.
- Free, with no token cost.
What it is good for
- Video delivery. Film, television and most video platforms expect 48 kHz, while music sessions are often at 44.1.
- Distribution specs. Get to 16-bit 44.1 kHz for a CD or a distributor that asks for it.
- Session consistency. Bring a borrowed stem or sample to the rate the rest of your project runs at.

Common questions
Does a higher sample rate sound better?
Not in any way most listeners can hear on a finished master. Higher rates are genuinely useful during production, where processing benefits from the extra headroom above the audible band. For delivery, 44.1 or 48 kHz is the right answer.
Should I deliver 16-bit or 24-bit?
Deliver 24-bit wherever it is accepted, because it leaves more room for the mastering and encoding stages. Drop to 16-bit only when a spec demands it.
