AudioAuditor analyzes audio files, including spectrograms and checks for fake lossless or AI-generated tracks.
WhatsMyBitrate
WhatsMyBitrate checks an audio file's bitrate, codec, sample rate, and frequency content, with an optional spectrogram.

About WhatsMyBitrate
WhatsMyBitrate is a web tool for checking the audio quality of a file. Users upload an audio file, and the site reports its codec, sample rate, channel layout and duration, along with an estimated bitrate, a lossy or lossless classification, and a result for the frequency content. The site's stated approach is to measure where the audio's frequency content ends and compare that point with the ceiling set by the sample rate (the Nyquist limit), rather than relying on the bitrate written in the file's metadata. A straight, unchanging cutoff is presented as a sign of a lossy transcode, and a cutoff that moves with the music is presented as a sign of a variable-bitrate encoder.
An optional spectrogram of the full track is available. The homepage describes it as a color map of frequency content over time. The homepage states that uploaded files are processed briefly for analysis and then discarded, and that nothing is stored or shared. The site also offers a debug log of each analysis.
Key features
- Estimated bitrate based on the frequency content of the audio
- Identification of codec, sample rate, channel layout and duration
- Comparison of the audio's frequency ceiling with the Nyquist limit
- Lossy or lossless classification of the uploaded file
- Optional spectrogram of the full track
- Debug log of the analysis
- Reads the frequency content of the audio instead of relying only on the file's stated bitrate
- Shows both the stated bitrate and an estimated bitrate, so the two can be compared
- Includes an optional spectrogram for visual inspection of the full track
- Analysis requires uploading the audio file to the site
