audio export not 320 kbps but 160 kbps

Hi Michael,

Is it possible to share(upload to Google Drive, One Drive etc.) the original clip so we can have a look?

It's possible that some video files include multiple audio stream in different bit rate. If this is the case, please make sure the audio stream you selected when import is more than 320kbps.

You just take a wav file and an image and do the test

Hi Michael,

Audio data in WAV is uncompressed. After you export to mp4, the audio is compressed by AAC encoder.

Isn't it make sense that compressed data will have less bit rate since less data need to be transmitted per second?

Also, in the screenshot above, 320kbps in MP3 is "Maximum bit rate", meaning that the encoder will output less bit rate if the audio data can be compressed more without losing quality.
