is there any updated hint as to when we will be able to save in Audacity, at 24 bit, or 32 float?

You can already export as 24-bit or 32-bit float.
See: https://manual.audacityteam.org/man/oth ... tions.html

RF64 supports large files and multiple channels.

From Audacity:
"File menu > Export > Export Audio"

Then select

File type: "Other uncompressed files"
Header: RF64
Encoding: Signed 16-bit

... but all I hear is static. Right... Compression is a lot like encryption. If you don't properly decompress it, the raw data is garbage. And with uncompressed files, the bytes have to be correctly re-assembled into samples, so you have to type-in the correct bit depth, sample rate, number of channels, ...

... to be clear - Audacity isn't editing the "file". The file gets decompressed and then Audacity works on the decompressed audio data. In the case of uncompressed WAV files, the samples are converted to floating-point data. Note that if you re-export to WMA or MP3 or other lossy format you are going ...

... damage by exporting a WAV file and shipping that around instead of the two options you mentioned. WAV (Microsoft) 16-bit are perfect quality, uncompressed sound files and don't seriously degenerate with repeated editing and saving. MP3 files create sound damage and they get worse and worse ...

... and if your player supports MP3 it will probably display the metadata (artist/title/song/etc.). If you are making a regular audio CD (uncompressed) it's better to avoid the (lossy) MP3 compression, but if MP3s is all you have, that's all you have, and making an audio CD won't make ...

... is playable with Win but is 111kB ( for 1 second) and should be about 8kB!! But the hellomco.com instructions say a sample rate of 62,500Hz. For uncompressed files: File size in bytes = (Bit depth/8) x Number of channels x Sample rate x Playing Time in seconds. For a raw file that's exactly what ...

Unfortunately the outputfile has 28kB for about 1 second audio. I guess the reason is, that audacity uses 32bit floating point. Your (confusing) hellomico instructions do specify saving as 16bit WAV at one point . There are RAW export options in Audacity ... https ://manual.audacityteam.org/man/oth...
