Audio Tools

Browser-based audio tools. Trim MP3 losslessly by copying frames rather than re-encoding, so the kept audio is unchanged. Supported local media processing; no signup and no watermark.

• Audio Cutter, Trim MP3 and other audio in your browser, the lossless mode copies the kept audio instead of re-encoding it.
• Normalize Audio. Match audio to a loudness target the way broadcasters and streaming platforms measure it, with a true-peak ceiling.
• Remove Silence. Cut the dead air out of a recording using a threshold measured against the material itself, with crossfaded joins.
• Change Audio Speed. Speed audio up or slow it down while the pitch stays where it was, or resample for the tape-speed effect.
• Noise Filtering, Clean background noise out of a recording in your browser, hiss, hum and room rumble go, the voice stays.
• Speaker Diarization. Split a recording into who-spoke-when: a speaker timeline with per-speaker talk time, built in your browser.
• BPM & Key Finder, Read a track's tempo and musical key in your browser, beat-accurate BPM from a small on-device model, key from classical chroma analysis.
• Vocal Remover, Split a song into vocals and instrumental with an on-device separation model, karaoke and acapella tracks from one pass.
• Voice Changer, Transform a voice with classic presets, deep, chipmunk, robot, telephone and more. Pitch, formant and effect chains on your device.

• Pitch Changer. Shift audio up or down by semitones and cents while the length stays exactly where it was.
• Audio Fader: Add a fade-in and fade-out to any audio file, with equal-power, linear or s-curve ramps, in your browser.
• Volume Changer. Turn audio up or down by an exact number of decibels, with a true-peak limiter that stops a boost from clipping.
• Reverse Audio, Play audio backwards in your browser, exact sample-order reversal with anti-click edge smoothing, per channel or whole file.
• Audio Joiner. Join multiple audio files into one, with equal-power crossfades or silent gaps at every seam instead of clicks.
• 10-Band Equalizer, Shape audio with a ten-band graphic equalizer, classic presets or your own curve, with clipping protection built in.
• Audio Visualizer: Turn a recording into a shareable PNG: an editor-style waveform, a log-frequency spectrogram, or both stacked on one time axis.
• Ringtone Maker. Cut any song or recording into an iPhone-ready .m4r ringtone, with edge fades and an automatic lift for quiet clips.
• Audio Converter. Convert any audio your browser can read into MP3, WAV, FLAC, M4A or OGG, with real quality tiers for each format.
