What the best way to convert Nintendo DSP MGSTTS by TheFuryFox at 9:42 AM EDT on October 3, 2016
Hello, I want to convert MGS TTS gamecube BGM to a usable format and foobar says that those files are lossless stereo 44100hz 16bit 403kbps and I want to convert them to Flac Ogg or Aac with the less amount of loss in quality and not too much filesize increase. For a 500kb DSP converted into Flac the size is >6MB and with Ogg with quality 0 it's approx 1MB What the best way(format, settings) to do this? And of course I want to merge L and R files to 4 or 2 channels stereo but it can be done.
Ogg (Vorbis) is probably the best compromise between size and quality, quality 0 is probably overkill, I usually use quality 3. Of course if you really want highest quality you need to use FLAC (or just keep the original source files, which are a lot smaller, but that doesn't seem to be an option for you right now).
As for merging, vgmstream will play the two paired files together as stereo; for instance if you play 0001L.DSP, it should find 0001R.DSP in the same directory and play them both together. Because you are seeing "lossless stereo 44100hz 16bit 403kbps" it seems like this is already working.
You need to convert only all the L files or only all the R files, otherwise you will end up with duplicates.
