Actually, the readme file that comes with the encoder says: "This program encodes WAV audio files to mp3HD files. The WAV audio files have to contain plain PCM samples in mono or stereo with a resolution of 16 bit per sample. The sample rate is restricted to one out of 32 kHz, 44.1 kHz, or 48 kHz." Anyhow, "proprietary" does not necessarily mean "secret". It doesn't make any sense to distribute an encoder or license a third party to develop an encoder and then not inform the end user what type of uncompressed files the encoder is capable of processing. I couldn't agree more that WavPack has a superior implementation of this concept, though. I don't understand what having lossy and lossless all in one file like mp3HD gets you. I mean, yeah, you can play back the file on a legacy MP3 player and it'll play the lossy version, but that means you have to but a gigantic file on your iPod or whatever just to hear regular MP3 audio that's not even encoded with LAME (meaning no gapless play, among other drawbacks). The separate correction file method that WavPack uses would be ideal, but hardware support is almost non-existent. What's kept me maintaining separate lossless and lossy libraries so far instead of going the WavPack-only route is mainly that I can't play WavPack files on my iPod short of reflashing it with the RockBox firmware, which I just personally don't care to use. It's a viable one-library solution to maintaining only one library if you do happen to have a RockBox-capable player and a SqueezeBox, however. -Steve _______________________________________________ discuss mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/discuss
