Analyze & Inspect
Audio Quality Analyzer
Detect upsampling, check spectrum, dynamic range, clipping and true bit depth.
Spectrogram Viewer
Visualize frequency content over time with adjustable FFT, color palettes, and dB range. Like Spek, in your browser.
Spectrogram Compare
Compare two audio files side by side. Spot upsampled, transcoded, or fake hi-res files with difference overlay.
Audio Metadata Viewer
Read and inspect ID3 tags, cover art, codec info, and embedded metadata from any audio file.
Waveform Viewer
Visualize the full waveform of your audio with zoom, pan, and channel separation.
Convert
Audio Converter
Convert between WAV, AIFF, FLAC, MP3, OGG, and AAC — all locally in your browser.
Video to Audio
Extract the audio track from any video file. Supports MP4, WebM, MOV, and more.
Sample Rate Converter
Resample audio to 44.1k, 48k, 88.2k, 96k, or 192k Hz with high-quality interpolation.
Bit Depth Converter
Convert between 16-bit, 24-bit, and 32-bit float with proper dithering.
Edit & Transform
Audio Looper
Loop audio files with crossfade, fade, gap, or reverse transitions. Set count or target duration.
Audio Trimmer
Cut and trim audio files with precision. Set start and end points visually on the waveform.
Audio Splitter
Split audio into segments by silence detection, time intervals, or manual markers.
Audio Merger
Combine multiple audio files into one with smooth crossfade, fade, or gap transitions.
Volume & Loudness
Adjust volume, normalize loudness to a target LUFS, or apply peak normalization.
Fade In / Fade Out
Add smooth fade-in and fade-out curves to your audio with adjustable duration and shape.
