If we are going to offer the granularity of any integer number between 98-320kbps then we really ought to be honoring the user's setting.īut My thinking is that it would be much better of Audacity limited itself to a set of practical rates as Apple does with Music/iTunes as can be seen in the image above in the Expected Behavior section.įlagging and as this is a UX/design issue as much as it is a technical Audacity/FFmpeg issue.ĪFAICT AAC-LC supports all modes that MP3 supports as well,Īs it has been previously discussed, we use something called native FFmpeg AAC encoder. Or the user can type into the quality fieldĪ) values below 98kbps are (silently) forced to 98ī) values above 320kbps are (silently) forced to 320 The user can use the up/down arrows to set the quality to be any integer value between 98kbps and 320kbps. Windows 10 and macOS 12.6.3 Monterey Additional context Updated tested results following an upgrade to the latest FFmpeg that recommendedġ60 - 196 (this is the default setting AAC export)ģ20 - 235 (this implies that 235kbps is the best we can achieve)ġ60 - 198 (this is the default setting AAC export)ģ.2.4 and 3.3.0 alpha master Operating system Ideally it would limit itself to offering only the practical stepped rates that say iTunes offers for its AAC conversions:
