Privacy Policy
Last updated: April 15, 2026
The short version
Most of our tools run entirely in your browser. Audio files stay on your device for those tools. A handful of tools require server-side processing, and we tell you clearly on the page before you upload anything.
Client-side tools (no upload)
These tools process audio entirely in your browser using the Web Audio API. Your files never leave your device.
- Audio Cutter — Trim MP3 and WAV files by selecting a start and end point on the waveform.
- Audio Merger — Combine multiple audio files into one with optional crossfade between tracks.
- Fade In/Out — Apply smooth fade-in and fade-out effects to your audio files.
- Volume Normalizer — Adjust audio volume to a target peak or RMS level. Simple, fast, client-side.
- Speed & Pitch — Change playback speed or shift pitch independently. Great for practice and remixing.
- Reverse Audio — Reverse any audio file instantly in your browser.
- Audio Recorder — Record audio from your microphone directly in the browser. Export as WebM or WAV.
- ID3 Tag Editor — Read and edit MP3 metadata — title, artist, album, year, genre, and track number.
- BPM Detector — Detect the tempo of any audio file using onset detection. Shows BPM with confidence.
- Waveform Viewer — Visualize audio waveforms with zoom and pan. Click to seek. Great for planning edits.
- Equalizer — Apply EQ bands to boost or cut frequencies. Preset profiles for voice, music, and bass.
- Stereo to Mono — Flatten stereo audio to mono. Cuts file size in half and fixes single-speaker playback.

- Tone Generator — Generate sine, square, triangle, or sawtooth test tones at any frequency.
- Noise Generator — Generate white, pink, or brown noise for sleep, focus, and speaker calibration.
Server-side tools (upload required)
These tools upload your file to our server for processing. The server uses ffmpeg to handle formats and operations the browser can't perform natively. Each of these tool pages shows a prominent disclosure before you upload.
- Silence Remover — Strip silent sections from audio. Tune the threshold, minimum duration, and preserve gap.
- Audio Compressor — Reduce file size by re-encoding at a lower bitrate. Choose from 32 to 320 kbps.
- Format Converter — Convert between MP3, WAV, FLAC, OGG, AAC, M4A, and Opus.
- Video to Audio — Extract the audio track from MP4, MOV, WebM, MKV, and AVI video files.
- Loudness Normalizer — EBU R128 loudness normalization with LUFS targeting. For podcasts, streaming, and broadcast.
- FLAC / M4A Trimmer — Trim audio formats the browser can't decode — FLAC, M4A, Opus, and more.
- Bulk MP3 Converter — Convert up to 20 files to MP3 at once. Downloads as a single ZIP.
- Vocal Remover — Subtract the center channel to thin or remove vocals — karaoke from any stereo track.
- Ringtone Maker — Cut a 15–40 second ringtone from any song with a smooth fade-out. M4R, MP3, or AAC output.
Server-side file handling
When you use a server-side tool, your file is uploaded over HTTPS to our processing server. Here's what happens:
- Your file is received and temporarily stored in memory.
- The server processes it (conversion, compression, normalization, trimming, or extraction).
- The processed result is returned to your browser.
- Both the original and processed files are deleted immediately after the response is sent. We do not retain copies.
We do not inspect, analyze, listen to, or store the content of your files beyond the time needed to process them.
Data we collect
We do not collect:
- Names, email addresses, account information, or login state
- Audio file contents beyond temporary server-side processing
- Browsing history or cross-site tracking data
Third-party services
MakeMySounds is hosted on Vercel. Server-side audio processing runs on the MakeMySounds processing API. We do not share your files with advertising or analytics providers.
Changes to this policy
If we change this policy, we'll update the "last updated" date at the top. For significant changes, we'll show a notice on the site.
