What is the difference between audio gain and volume, and how do they affect the sound quality of a recording or playback?

Audio gain refers to the amplification of the signal before it is processed, while volume refers to the level at which the audio is played back. Adjusting audio gain can impact the overall quality and clarity of the recording, while adjusting volume can affect the perceived loudness of the playback. Improperly setting audio gain can introduce noise or distortion, while adjusting volume too high can lead to clipping and distortion. Balancing both factors is crucial for achieving optimal sound quality in recordings and playback.
