How the telephone filter works

Try it on a phone conversation in a sketch, a distant caller's voice in a game or a lo-fi section of a song. It's a stylized effect, so it won't match every kind of phone.

The Default preset cuts bass below 400 Hz and treble above 3,000 Hz, boosts the midrange near 1,400 Hz and uses compression to even out the level. A little distortion adds the rough edge. The other presets change the filtering and add crackle or tape hiss.

Keep your original if you'll need the full sound later: saving as WAV won't bring back the bass and treble the filter removes.

Only need one line? Trim the recording first. To adjust the volume without adding an effect, use Normalize Audio.
