Audio Effects
Free online music filters and audio effects
Choose an effect for the sound you want
Choose a music filter to change the sound of an existing recording. Use EQ for bass, vocals and treble, reverb for ambience, or gain for volume. These effects process audio locally and let you compare the result with your original.
For tempo and pitch edits, try Nightcore, Nightcore Reverse, Sped Up, Slowed + Reverb, TikTok Slowed or Vaporwave. Each opens with its own starting settings that you can refine. Try the built-in demo, listen to your original and processed audio separately, then export WAV, MP3 or AAC. These tools are free and process audio on your device.
