Tools for Audiophiles
18 toolsFor careful listeners: test speakers, headphones and a subwoofer, inspect a file's spectrum and bitrate, compare two versions blind, set up an equalizer, build a 5.1 disc for a home theater and set the turntable speed with a strobe disc.
Audio
Equalizer
Professional 10-band equalizer with real-time preview, spectrum analyzer, and 14 presets. Adjust bass, treble, mids, apply high/low-pass filters — all directly in your browser.
Convert Audio
Convert audio between MP3, WAV, FLAC, OGG, AAC and 35+ other formats. Batch up to 500 files — adjustable bitrate, sample rate, and quality.
Audio Player Online
A player for people who listen closely: it plays the ordinary formats and the ones the browser does not know, reads CUE albums, shapes tone with 31 bands and matches loudness between recordings.
Audio Restoration
Bring old recordings back to life. Diagnose noise and clicks, apply per-source presets, repair the spectrogram, target broadcast loudness.
5.1 Surround Disc Image for Home Theater
Build surround audio into a DVD-Video disc with chapters, AC-3, multichannel FLAC, a DTS track or an ISO image. Online, in your browser.
Analysis
Ear Trainer
Hearing which frequency is the problem is a skill built by repetition. Everything you need for that is here.
Audio Inspector
Inspect audio files for true quality — detect upsampled or re-encoded tracks by analyzing the spectrum.
Audio Comparator
Compare two audio files side-by-side with objective metrics — LUFS, spectrum, dynamic range, ABX blind test, sample-level diff.
Audio Metadata Editor
View, edit or strip ID3 tags, cover art and comments via WebAssembly
Device Testing
Speaker & Headphone Test
A voice names each channel — “Left”, “Right” — so you hear at once if it is wired right. Balance in dB, 5.1/7.1, frequencies, no-sound finder.
Speaker Cleaner
Water eject at 165 Hz, a dust sweep, and a microphone check that tells you whether the sound actually changed.
Subwoofer Test
Test your subwoofer with tone generator, frequency sweeps, bass drops, diagnostics, and room mode calculator.
Bluetooth Audio Test
Test any Bluetooth audio device: headphones, speakers, earbuds, car audio. Measure latency, check speaker channels, test mic quality.
Measuring
Samples & Test Files
Sample Audio Generator
Download or generate sample audio for testing — 1 kHz tone, pink noise, custom sine/white/pink at 44.1/48/96 kHz, 16/24-bit, mono/stereo WAV.
Sine Sweep WAV Generator
Generate log or linear sine sweep WAV files for REW, ARTA and room measurement. 20 Hz–20 kHz, 44.1/48/96 kHz, 16/24-bit, full channel routing.
