Want your voice to sound like a phone call, a song with more bass, or a funny chipmunk clip? Attach the audio or video to ToolGPT and describe the sound. It shows the effect presets, you tap one, and the new file is made in your browser.
Slapback, Echo, Bass, Treble, Telephone, Deeper and Chipmunk, plus “As it is” to leave the sound alone.
No preset makes the file longer. On a video, the picture is copied untouched and stays in sync.
Bass, Treble and the echoes make audio louder. The cards measure your file's peak level and say when loud parts would distort.
Deeper and Chipmunk accept any shift from seven semitones down to seven semitones up.
Use it on an audio file or on the soundtrack of a video.
The effect is applied on your device, and the original file is never modified.

Slapback adds one short repeat close behind the sound. Echo adds three softer repeats. Bass lifts everything below about 120 Hz by 6 dB. Treble lifts the top end by 5 dB.
Telephone keeps only the 300 to 3,400 Hz band a phone line carries, so the sound turns thin. Deeper moves the pitch down four semitones, and Chipmunk moves it up seven. You can also ask for a different shift, such as “two semitones down”.
Every preset keeps the file exactly as long as it was. The last repeat of an echo is cut off at the end instead of making the file longer. On a video, only the sound is processed and the picture is copied as it is, so even a long video finishes much faster than a full re-encode.
Each request applies one effect. To combine two, apply one and then the next to that result. Each step encodes the sound again, so fewer steps keep more quality.
There is no reverb. ToolGPT leaves it out on purpose, because a reverb that is not tuned by ear tends to sound worse than none. To make a whole file louder or quieter, ask ToolGPT to change the volume, which is a separate tool.
An MP3 comes back as an M4A after an effect, because browsers have no built-in way to write MP3. Ask ToolGPT to convert the result to MP3 if you need that format.
Not at the moment. The presets are Slapback, Echo, Bass, Treble, Telephone, Deeper and Chipmunk.
Browsers have no built-in way to write MP3, so a processed MP3 is saved as an M4A. Ask ToolGPT to convert the result to MP3 if you need one.
Yes. The effect is applied to the video's sound, and the picture is left exactly as it was.
No. Effects are applied in your browser.
