Hi folks, anyone have experience transcoding native .aea files from a MiniDisc to 32-bit uncompressed floating point? I was able to upload using a USB-connected Sony MZ-RH1 via QHiMDTransfer for Mac OS, then opened the files in VLC. Successfully saved using Streaming/Transcoding Wizard but I have no idea if all of the raw data was preserved at the highest bit-depth. (The resulting WAV files are 10x the size of the originals.) Does anyone know exactly how VLC handles the data? Much obliged!

Depends how. If you used s32l, yes.

Jean-Baptiste, Thank you for your reply.

So what is s32l? (A setting in VLC or are you referring to something else?) In VLC I had a choice of 32-bit integer or 32-bit floating point and chose floating point. Specifically:

In VLC 2.0.9 (not the latest) I followed these steps in the Streaming/Transcoding Wizard menu: Audio > Transcode audio > Codec: Uncompressed, floating point > Bitrate: [doesn't matter; output file size unaffected] > Encapsulation format: WAV. The Transcode/save took about 10 seconds to output a 393MB WAV from the original (18 minute long) 41 MB .aea file. Which means it wasn't doing much processing at all, a good thing?

Also, the options in VLC 2.2.4 (latest) are different and I couldn't figure out how to perform the same transcode as with previous version software.

Thanks again!

Last page of transcode wizard gives you the "sout" option that was used. You can use that to recreate it in 2.2.4
