Analyze
Look inside an audio file: waveform, spectrum, spectrogram, loudness, clipping, codec details and raw WAV structure, or compare two files side by side.
- Audio AnalyzerAnalyze an audio file: waveform, spectrum, spectrogram, loudness, peaks, clipping, DC offset and stereo phase, with a plain-language summary.
- Audio File InfoSee the codec, bitrate, sample rate, bit depth, duration, channels and container of any audio file. Check several files at once. Runs on your device.
- Spectrogram ViewerView a spectrogram of any audio file with zoom, log or linear frequency, colour maps and PNG export. Spot fake lossless files by their cutoff.
- Spectrum AnalyzerSee the live frequency spectrum of a playing file or your microphone, with peak hold and a choice of FFT size and scale. Runs locally.
- Waveform Image GeneratorTurn any audio file into a waveform image. Choose colours, size and bar or line style, and download it as a PNG or SVG. Runs on your device.
- Loudness Meter (LUFS)Measure integrated, short-term and momentary loudness, loudness range and true peak to EBU R128 and BS.1770, and compare with streaming targets.
- Clipping DetectorFind clipping in an audio file: how many samples reach full scale, how many in a row, and where. See the worst spots on the waveform.
- Compare Audio FilesCompare two audio files: properties side by side, stacked waveforms, loudness, a null test and A/B playback that switches instantly, in sync.
- WAV Header ViewerInspect the structure of a WAV or AIFF file: fmt, data, fact, LIST, bext, iXML, cue, smpl and ds64 chunks with offsets and sizes. Runs on your device.
