FAQ
What does it sound like?
A thin, boxy voice squeezed into the narrow band a phone line carries — like a call or voicemail.
How is it different from Radio?
Telephone stays clean like a call; Radio adds crackle and movement like a broadcast.
What source works best?
Clean, close-mic speech — the filter only keeps the narrow midrange, so a clear recording sells the phone-line illusion.
Supported Formats
Input: audio/video. Output: MP3, WAV, OGG, FLAC, M4A, MP4.
What the telephone effect does
It cuts the deep lows and airy highs, keeping only the narrow midrange band a phone line carries. That thin, boxy tone instantly reads as a phone call or voicemail.
Telephone vs radio
Both narrow the sound, but telephone stays clean and clear like a call, while Radio adds crackle and movement like a broadcast. Pick telephone for dialogue and call scenes.
