The audio compressor automatically adjusts and maintains the signal levels as they go to H/Disk or Tape to be recorded. This compression evens out the distance between loud & quiet parts, by crushing the audio if it gets too loud, and raising the audio in the quiet sections. Compressors also can radically beef up a synth bass sound for example, making it sound tight and punchy.
If you are recording any type of audio, especially vocals, you can use the audio compressor in MP3 Editor for Freeto smooth the region between loud and quiet parts.
Follow the lead to apply compressor effect:
To add a compressor effect, you firstly need to launch MP3 Editor for Free and add an audio file to the waveform window. Then click “Effect” tab and choose “Compressor” to specify detailed parameters or apply some popular presets to adjust the effect. Click “Preview” to listen to the music before adding the effects to the waveform to make sure you get exactly what you want. Click “OK” to add the compressor effect to the selected region.
