which is the best lossy codec for....

I've already read something about transcoding from lossy to lossy files, but these reports I found on HA.org are some about 4 years old or not very informative.

Informations about lossy transcoding was found here:

The reason I / we don't convert our cd storage to lossless is because compression is still too high. Taking around 450 mb / cd is clearly too much.

Moderate quality / filesizes brought us wavpack lossy @ 384 (-b384x3)

also tried MPC @ --insane


Question: From which codec is it the best way to transcode from (mostly to MP3Lame3.97 @ -V 2 --vbr-new)?

Would MPC be recommended? or is it better to use WavPack lossy at all?

MPC offers great quality and so on.. but I'm afraid of transcodingbecause so many say transcoding from a psychoacoustic model to an other is worse than transcoding from a codec without psychoacoustic models.

thx for (useful) replies

Guruboolez, someone with very sensitive ears, did a Short re-encoding blind listening test in 2005.

The initial test was to convert 261 kbps sources (including Musepack and Wavpack hybrid lossy) to LAME 128kbps ABR.

MP3 -V0 --vbr-new came out clearly the worst. MPC -quality 7.5, OGG aoTuV -q 8.3 and WV -hb256 came out very close as best, with Wavpack being slightly lower than MPC and OGG in this test, though not by a statistically significant margin.

Later in the thread he indicated that WV approached transcoding transparency compared to direct CD->MP3 at 400 kbps, but he could just ABX it.

At 350 kbps, WV was clearly better than MPC at -q10 (similar bitrate), but Vorbis wasn't tested.

The results from transcoding to LAME -V2 --vbr-new will be different again, but I do wonder why you just don't encode to LAME -V2 --vbr-new in the first place, having results that are essentially transparent (indistinguishable from the other settings you mentioned) for almost all music at about half the bitrate of your Wavpack lossy and 2/3 the bitrate of MPC -q7 and which can be played on virtually any music player in existance.
