Answering a query at talkbass, I said:
- It is my understanding (anecdotally) that WAV may be superior to AIFF – I do not use the latter as I am on a PC and have no need, YMMV.FLAC is “lossless” compression, and IME if you use the highest quality compression, it truly is. You can take a WAV, convert to FLAC, convert back to WAV, flip the polarity and it cancels out the original WAV.
- There is a theory that 48 is better than 44.1 due to less math being involved. I use 44.1 as that is standard for CD’s and I prefer to avoid conversions, for time/efficiency reasons is if nothing else. To the extent that I ever heard a difference between them (not sure I really did), it is not a case of one sounding better than the other …
- I will add that IMO bit rate is the more important variable on a practical level – while I can hear 96kHz [and dislike the top end] there is a significant improvement in 24 bit vs. 16 bit in depth and realism – the infamous “remove the gauze” effect, but subtler. Q.E.D., I use 32 bit float [a mathematical variation on 24 bit that may benefit processing], 44.1 WAV to record and mix.)There are other compression formats like OGG and MP3. A 320kps MP3 is very close to a WAV for listening purposes, but will suffer if you process it.
- All that said, the issue with file compression in recording is degradation, which does mean math stuff (artifacts, distortion, etc.) if you try to process – including mix – a compressed file (or even one converted back to WAV, as there is less data, see below) – it may or may not be audible.
- The issue with file compression in playback is that the file contains less data, typically bandwidth-limited (file compression can be thought of simplistically as removing the extra zeros in a binary file – finer information detail gets potentially lost and/or more easily corrupted) …
- But do keep in mind the method of monitoring/playback. Internet sites like Soundcloud and Bandcamp, etc. have their own players which themselves may change the sound versus other playback methods – I can hear it on Soundcloud, and the old MySpace was notorious for this. So if you are uploading for someone to listen, 320MP3 is great – (internet standard has long been 128kps with low-end narrowing), and I even on occasion use 320 tracks (converted to WAV) in file exchange recording, where it is one track in a multi-track mixdown.
- But generally speaking, IMO, you want 16 bit 44.1 in your fave format. I, BTW, use WAV but could use FLAC with my DAW (CEP2.1) – I convert to FLAC at highest settings with sound-shaping and dither for uploads to Bandcamp as the end of my mastering process (in Reaper).
- DISCLAIMER: I am not an expert, and the above info is what I use to function – you should do your own research, but many of the concepts above might help you get started.
