Drop the file into WUJIEE Audio Tools and it reads out duration, sample rate (Hz), channel count and estimated bitrate (kbps) in seconds — no professional software required.
It is computed as file size divided by duration — for variable-bitrate (VBR) files it's an average and may differ slightly from the encoder's nominal value.
Read-only. Privacy-sensitive parsing happens on-device, the data is destroyed when you close the page, and the original file stays untouched.
Check the sample rate (e.g. 44.1kHz), bitrate and channels here against the platform's requirements first, then use Convert Audio only if something needs changing.
