Whenever I save an audio clip as a new file, it always exports at a rate of 1,536kb/s. This is astronomically huge, considering that, when exporting a video clip, the audio portion of that clip can only export at a maximum of 320kb/s. It seems that the most HDD-efficient means of saving an audio-only clip is to export it as a video with a black screen with a resolution of 176x144.
Is there any menu that lets me select the bitrate when I save an audio clip as a new file?
