set_audio_bitrate
Adjust the audio bitrate of a file to a specified target value. Input the source file, define the target bitrate, and save the output for optimized audio quality in video and audio editing workflows.
Instructions
Sets the bitrate for an audio file. Args: input_audio_path: Path to the source audio file. output_audio_path: Path to save the audio file with the new bitrate. bitrate: Target audio bitrate (e.g., '128k', '192k', '320k'). Returns: A status message indicating success or failure.
