Check a WAV file before you send it
Inspect an exported WAV’s format and levels before sending it to a collaborator or importing it into another session. This file checker reads the original header and audio samples, so you can compare the result with the export settings you intended to use.
- Choose a PCM or IEEE float WAV file up to 50 MB.
- Check the sample rate, bit depth, channel count and duration against the requested format.
- Review the sample peak, RMS level and quiet edges. Listen to the file in your player or DAW if a measurement looks unexpected.
- Download the JSON report if you want to keep the measurements with your project notes.
Understand your WAV measurements
- Sample rate is the number of samples per second, such as 44,100 Hz or 48,000 Hz. The checker reports the rate stored in the file header.
- Bit depth and encoding describe how samples are stored. Check both when a collaborator asks for a particular PCM or floating-point format.
- Sample peak is the largest stored sample magnitude, expressed in dBFS. It is not a true-peak measurement.
- RMS level measures average signal energy across the file. It is not integrated LUFS and does not rate the quality of a mix.
- Quiet edges are leading and trailing samples below −60 dBFS across every channel. An intro or reverb tail can make these regions intentional.
Use the result to check your export settings
If a collaborator requests stereo, 24-bit PCM at 48 kHz, compare each property with the report. If something differs, revisit the export settings in your DAW and check the new file. These measurements help verify technical properties; they do not certify a release or guarantee a distributor will accept it.
WAV file checker questions
Do full-scale samples mean the audio is clipped?
Not necessarily. Samples at the format’s full-scale boundary deserve a listen, but they do not prove audible distortion. Floating-point files can also contain values beyond ±1. This check does not detect intersample peaks or replace a true-peak meter.
Does a higher sample rate or bit depth prove better quality?
No. The header describes the current file format, not the recording’s history. Converting a lower-resolution source into a higher-resolution format does not recover detail missing from the source.
Which WAV formats are supported?
Standard RIFF WAV files with 8-, 16-, 24- or 32-bit PCM, or 32- or 64-bit IEEE float samples, up to 50 MB. Compressed WAV, RF64 and big-endian RIFX files are not supported.
Is my audio uploaded or changed?
No. Analysis runs on your device. The tool does not upload or save your audio or filename, and it never changes the original file. The report is downloaded only when you choose to save it.
