Exciting update - new high quality downloads soon!
Added 2020-12-31 23:28:21 +0000 UTCExciting Update - I nearly finished the metadata file and now I am working on the converter. There is maybe 10 hours left of work to do, and then it is done forever!
It will build the complete library in default, 320kbps 16 bit mp3, 540kbps 32 bit AAC, ogg, etc and attach all the album art and description to the song, so can access it from your iPhone, fancy car stereo system, etc. It is pretty fancy and the script will publish the entire. For me, this automates a painstaking process which would usually require 20 hours of tedious busywork, copying and pasting items from spreadsheets and uploading files into a simple button push.
If you have any thoughts on audio file formats please let me know, I am gravitating toward not including true lossless flac, since the file sizes seem huge. But instead providing the 32-bit files in AAC which is the most accepted file format , I figured something like 540kbps would be enough for that I will try it out and see. Either way it will be trivial to add more formats after the fact. Everything will be encoded directly from the 32-bit wav masters for the highest quality, with no transcoding.
I am using ffmpeg for the conversion and will try to attach the id3 metadata so it appears fancy on your mp3 player too and in iTunes. I will try to make sure all the encoding settings are the best possible. I was also going to do ogg, but that is only 24 bit padded to 32 bit so I thought that AAC would be a better tradeoff?
The script will also update the store for me and output some fancy spreadsheets and liner notes for each album, including the set list, song playing time, and total set playing time, and additional notes about the album overall theme and about the quality and techniques used for compression.
As you can imagine I am pretty excited and you will be among the first to know when it's done.

I would use FLACs and AACs - whatever format is understood by current production iOS. I like the idea of ogg but I won’t use ‘em.
2021-01-01 04:58:52 +0000 UTCBWNautilus one thing I was doing was finding a real whispery part in the wav file that generated a peak in my FFT around 20kHz way up there high, and then checking the mp3 to see if I saw a similar peak. The 320 kbps mp3 does not show that same peak although there is not really any audible difference between it. So when we run the same test on the Flac file, it should show the whispery part and then we know that it is truely lossless audiO :) am excited!

2021-01-01 00:14:07 +0000 UTCThanks for your reply. 16 bit FLAC it will be. I will check the files for quality but if you also want to make sure it meets your requirements that would be great.
