Technical information for an audio file (WAV)
Quickly check the technical characteristics of a WAV file: duration, sample rate, channels, resolution. 100% local processing in your browser (WebAssembly) — nothing is sent to a server.
Drag and drop a .wav file here, or click to select it (max 200 MB).
How it works
Useful before importing an audio file into an editing program (to check that it matches the sample rate expected by your project, for example 44.1 kHz or 48 kHz), or simply to understand why a received file seems too large or of poor quality. The tool reads the WAV file's header — without decoding all the samples — and directly displays the technical information stored there.
Why does the sample rate matter?
It determines how many times per second the sound was measured (44,100 Hz is the standard for audio CDs, 48,000 Hz for video). Mixing files with different sample rates in the same edit can cause offsets or a quality drop if the software doesn't correctly convert them beforehand.
What do "mono" and "stereo" mean?
A mono file contains only a single audio channel (identical for left and right), while a stereo file contains two, allowing sound spatialization. A "multichannel" file (more than 2 channels) is generally intended for a surround sound system.
