21、P TS 26.177 version 15.0.0 Release 151 Scope The present document specifies the digital test sequences for the DSR Extended Advanced Front-end speech codec. These sequences can be used to test for a bit exact implementation of the DSR Advanced Front-end codec and quantization (3GPP TS 26.243). 2 Ref

22、erences The following documents contain provisions, which through reference in this text, constitute provisions of the present document. - References are either specific (identified by date of publication, edition number, version number, etc.) or non-specific. - For a specific reference, subsequent

23、revisions do not apply. - For a non-specific reference, the latest version applies. In the case of a reference to a 3GPP document (including a GSM document), a non-specific reference implicitly refers to the latest version of that document in the same Release as the present document. 1 3GPP TS 26.24

29、(2018-07)63GPP TS 26.177 version 15.0.0 Release 155 Test sequence format 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 archiv

30、e 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

31、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. 6 DSR test sequences

32、 Forty-three encoder input sequences are provided, 22 with 8kHz sampling, 23 with 16kHz sampling. 8kHz sampling: T00.INP - T21.INP as described in the AMR test sequences document TS 26.074 4. 16kHz sampling: T00.INP - T22.INP as described in the AMR WB test sequences document TS 26.174 5.
