[Request] Original Quality

[pleasantarmour]

It would be nice if there was an option to use the original quality settings of the audio files being merged. Sample Rate, Channels, and Bitrate information will be taken from the original files and applied to the newly merged files, thus retaining the file size and quality.

👍 My files balloon up when I join them.

Would be nice if it did not resample them at all. I created my audio files in m4a format, but I can create in any format to make the merge easier for your tool.

Just started using AudioBookBinder and I'd really like to see this feature.

Since this ticket is like, 5 years old I will assume it's either hard or not a priority. If it's something straightforward and someone can point me to the right direction I'd like to give this a shot.

Audiobook Binder has been stagnant for number of years, mostly due to lack of spare time and other priorities.

The technical part of this FR is not super hard. The quality settings of the encoded stream are configured here:
https://github.com/gonzoua/AudioBookBinder/blob/master/AudioBinderWindowController.m#L719

The input stream info can be obtained using Audiotoolbox API, see AudioFileGetProperty calls in AudioFile.m. See https://developer.apple.com/documentation/audiotoolbox/1576499-audio_file_properties?language=objc

This would be a major improvement for the software. I will try to implement this soon.
