To make your track louder or easier to listen to, upload the audio file, select the level of compression, and click “Compress”.
Compression increases the volume by first decreasing the volume of the louder parts. Then makeup gain is applied to the whole track and the new loudest parts are brought back to 0 Decibels. This can enhance a track that was recorded too quiet.
