How the result is calculated
The Web Audio API decodes every bounded source at one sample rate. A chunked local PCM writer appends the complete clips in file-picker order, duplicates mono only when stereo output is needed and inserts the selected silence between clips. The result is uncompressed WAV; tags, artwork and source compression are not retained.
Method source: MDN decodeAudioData documentation.
All calculation and transformation work happens in this browser tab. No entered value is sent to an Noler Tools application server.
Important limitations
Results are provided for convenience and should be checked independently before an important decision. A format or checksum result never authenticates an identity, document, account, licence, vehicle or registration.
