Trial: A-weighted level demo

Upload a short WAV clip and see the A-weighted equivalent continuous sound level in 1-second intervals (LAeq,1s). Up to 5 minutes.

Free demo (≤ 5 minutes)

No account required. Upload a WAV up to 5 minutes long. The demo returns A-weighted broadband LAeq and a 1-second time history. Use the full product for longer files and band spectra.

.wav only, mono or stereo. Clip length may be limited on the server side.
Adds this offset to the measured level.
What this demo does
  • Applies an A-weighting filter to your audio.
  • Computes 1-second equivalent continuous levels LAeq,1s.
  • Displays the time history and basic statistics.

In the full product, you can also compute 1/3-octave spectra, broadband levels and FFT outputs, and export all data.
