lossyWAV Development
That's got it working! Thanks for the quick reply! Batch files make me nostalgic for DOS 3.3 -- NOT! Before I waste lots of time, assure me that there'd be no benefit taking a lossy.flac and converting it into MP3, AAC (HE, LC), OGG or some other lossy. (That's as an alternative to using a lower quality in the native encoder, thus relying on the inbuilt psychoacoustic tunings.) I just started thinking about creating Nero LC-AAC files from your semi-lossies as an alternative to HE-AAC for my Sony-Ericsson musicphone... Garf claims HE-AAC isn't battery-thirsty (though it is CPU hungry), but I have doubts. Glad to be of service . The added compression in certain lossless codecs is only due to the exploitation of the wasted-bits mechanism. Transcoding from a lossyWAV processed lossless files has not (to my knowledge) been well explored yet. @halb27: I've been looking at making spreading functions for all of the FFT lengths more conservative. I'm trying: 22222-22222-22223-12233-12234-12234 and although the bitrate goes up a bit, it may be attractive.
