Frequently Asked Questions
What does the phone call effect do?
It limits the audio to the narrower frequency range associated with telephone speech, boosts the midrange, evens out volume, and adds a small amount of digital texture.
Why does the result sound thinner?
That is intentional. Phone systems remove deep bass and very high frequencies, leaving the focused midrange that makes speech recognizable.
Does this work best on voice?
Voice is the natural fit, but the effect also works well for lo-fi music passages, game dialogue, radio chatter, sketches, and sound design.
Is my audio stored?
No. The file is streamed to the audio processor for this conversion and the temporary processing files are deleted immediately afterward.
