This clause provides information on the format of the digital test sequences for the DSR Extended Advanced Front-end (TS 26.243 [1]).

5.1 File format

The test sequence files in PC (little-endian) byte order are provided in archive files (ZIP format), which accompany the present document.

Following decompression, three types of file are provided:

*.inp – Input to the speech encoder.

*.cep – Cepstral output of the encoder, input to the quantizer.

*.pitch – Pitch output of the encoder, input to the quantizer.

*.class – Class output of the encoder, input to the quantizer.

*.vad – VAD output of the encoder, input to the quantizer.

*.bs – Output of the quantizer

Two test scripts are provided for exercising the Extended Advanced Front-end and quantizer functions.

All file formats are described in 3GPP TS 26.243 [1].
