Do you have a source on the CoreAudio quality thing? I'd be very interested in reading more about that. -------------- next part -------------- An HTML attachment was scrubbed... URL: http://lists.xiph.org/pipermail/flac-dev/attachments/20150719/f37ce5e8/attachment.htm

[flac-dev] Apple afconvert & SRC (was: FLAC implementation in Windows 10)
Sorry for the non-FLAC content, but I will say that a utility like afconvert that also supported FLAC would be great. It would be very useful to be able to convert directly from a FLAC that is very large to a CAF, since the latter can exceed 4 GB without breaking the format.

It would be very useful to be able to convert directly from a FLAC that is very large to a CAF, since the latter can exceed 4 GB without breaking the format. >If GStreamer has a plugin that can encode CAF, you can make a pipeline for that easily (alternatively, avconv might do as well; though in that case GStreamer should be able to, via gst-libav). The advantage here is that there's no inherent duration/size limitation within the pipeline. If that won't work, you might be able to feed a separate CAF encoder, if it accepts data from stdin, but in that case it is very likely to trip over some limit (like 4GB or some other WAV-y thing; most of the time these kinds of tools expect RIFF WAV as input). Either way, it's not FLAC that's the problem here. -- O< ascii ribbon - stop html email! - www.asciiribbon.org -------------- next part -------------- A non-text attachment was scrubbed...
