If I create a mono M4A file using 0.6.1 and then try to > import it using a v0.5 library, it will always import as stereo. So if you import the 0.6.1-created mono file on Mac using 0.6.1, it's mono? A mono M4A created by Audacity on Ubuntu using 0.6.1 still imports as stereo into Audacity on Windows using FFmpeg 0.6.1 (as supplied in your installer).

Also speed of WMA and AC3 exports are comparable to other formats for me. So for you (from a generated tone), how much slower are M4A exports using "M4A Files" and FFmpeg-with-native-AAC encoder, compared to other formats? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/602934 Title: ffmpeg import/export not working with ffmpeg version in maverick -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
