ANALYSIS & SPECIAL TOOLS
These actions use your loaded audio and run in this browser.
BPM is an estimate. Vocal removal uses center-channel cancellation and works best when vocals are centered in a stereo mix. Pitch and tempo change together in this version.
CREATOR TOOLS
Record, combine and refine
Microphone recorder
Record from your microphone and load the resulting WAV into the studio. Allow microphone access when prompted.
Ready to record · max 5 minutes
Audio joiner
Choose two or more files in the order you want them joined. Optional crossfades smooth transitions.
Select at least two audio files.
Silence remover
Detect quiet gaps and export a new WAV with long silent sections removed. The original loaded audio stays unchanged.
Load audio to detect gaps.
Mastering and loudness
Use compression for more consistent dynamics, analyze the loaded source peak/RMS level, and normalize the exported result to a peak target.
Analysis measures the loaded source, not effects output. RMS is not integrated LUFS.
ADVANCED AUDIO WORKSPACE
More control, bigger projects.
Batch-process files, build a simple multitrack mix, reduce steady background noise, or create an audio visualizer video. These tools run locally in your browser.
BATCH
Batch audio processor
Apply one preset to several tracks and download the processed WAV files in a ZIP. Files stay on this device.
Select up to 12 audio files. Output is WAV inside a ZIP.
MIXER
Multitrack editor
Layer up to 12 audio clips. Set each clip's start time, level, pan, and mute state, then render a stereo mix.
0.0s
Add one or more tracks to begin. Clips start at 0 seconds until you change their offsets.
Up to 12 tracks · maximum mix length 10 minutes.
Download mixed WAV
SPECTRAL
Advanced noise reduction
Estimate a noise profile from the beginning of a recording, then apply spectral subtraction. Use a section that contains only background noise for best results.
Local spectral subtraction · limit 90 seconds per file. Avoid choosing a profile containing speech or music.
CLIPSCONVERT AUDIO
Advanced Audio Visualizer Studio
Build a custom music visualizer with different animations, layouts, themes, title placement, background images and editable credit text. Preview locally and export a WebM video when your browser supports recording.
Exports render in real time. Full HD, 60 FPS and very high quality use more memory and CPU. Browser export is WebM; MP4 is not generated by this tool.
Select an audio file. Maximum length 5 minutes.
Download ClipsConvert Audio video
These advanced tools run locally in your browser. Batch processing outputs WAV, the multitrack mixer renders WAV, and the visualizer exports WebM when the browser supports MediaRecorder. Spectral subtraction may leave musical artifacts and is not AI source separation.

GOOD TO KNOW
Frequently asked questions
Are my audio files uploaded?
Effects and WAV export are processed in your browser. If you choose MP3 export, the processed audio is sent to this server for encoding only after you check the consent box.
Which formats can I export?
WAV is rendered locally in your browser. Recorder, joiner, silence-cut export, and mastering tools run locally. MP3 export requires FFmpeg on the server and, after your explicit consent, uploads only the already-processed audio for encoding. Input format support depends on the browser.
Does playback speed preserve pitch?
No. The speed control uses playback-rate adjustment, which changes both speed and pitch. Pitch-preserving time stretching requires a dedicated DSP algorithm.
Can I use this on a phone?
Yes, the layout adapts to mobile screens. Large audio files may take longer to decode and process on mobile devices.
