Test Sequences for the 4403's Audio Wavefile Replay Function |
From software version 3.10 onward, the Audio Option of the 4403 allows to replay audio files in a given format (for details please check the manual). Here we offer standard wave files for the test sequences given in GSM specification 06.54 ("Test sequences for the GSM Enhanced Full Rate (EFR) speech codec"). There are two zipped files for download:
Wav_16kHz.zip, contains the test sequences with a 16 kHz sampling rate, which has to be used when the signal destination is AF Out. (file names are: t1_16k.wav .... t19_16k.wav)
|
|
|
Wav_8kHz.zip, contains the test sequences with an 8 kHz sampling rate, which has to be used when the signal destination is Codec in. (file names are: t1_8k.wav .... t19_8k.wav)
|
|
|
These zip files have to be unzipped onto a floppy disk and copied to the hard disk of the 4400, into subdirectory /rapid/wav. This needs to be done within the RAPID! environment.
The following sequences are available:
- TEST1.INP - Synthetic harmonic signal. The pitch delay varies slowly from 144 down to 18.5 samples. Amplitudes at saturation point -4096 and +4095.
- TEST2.INP - Sinusoidal sweep varying from 150 Hz to 3400 Hz. Amplitudes ± 1250.
- TEST3.INP - Sinusoidal sweep varying from 150 Hz to 3400 Hz. Amplitudes ± 4000.
- TEST4.INP - Female speech, active speech level:
-19.4 dBov, flat frequency response.
- TEST5.INP - Male speech, active speech level:
-18.7 dBov, flat frequency response.
- TEST6.INP - Female speech, ambient noise, active speech level:
-35.0 dBov, flat frequency response.
- TEST7.INP - Female speech, ambient noise, active speech level:
-25.0 dBov, flat frequency response.
- TEST8.INP - Female speech, ambient noise, active speech level:
-15.6 dBov, flat frequency response.
- TEST9.INP - Female speech, car noise, active speech level:
-35.5 dBov, flat frequency response.
- TEST10.INP - Female speech, car noise, active speech level:
-26.1 dBov, flat frequency response.
- TEST11.INP - Female speech, car noise, active speech level:
-15.8 dBov, flat frequency response.
- TEST12.INP - Male speech, ambient noise, active speech level:
-34.9 dBov, flat frequency response.
- TEST13.INP - Male speech, ambient noise, active speech level:
-24.8 dBov, flat frequency response.
- TEST14.INP - Male speech, ambient noise, active speech level:
-15.0 dBov, flat frequency response.
- TEST15.INP - Male speech, babble noise, active speech level:
-34.1 dBov, flat frequency response.
- TEST16.INP - Male speech, babble noise, active speech level:
-24.3 dBov, flat frequency response.
- TEST17.INP - Male speech, babble noise, active speech level:
-14.4 dBov, flat frequency response.
- TEST18.INP - Female speech, ambient noise, active speech level:
-26.0 dBov, modified IRS frequency response, with many zero frames.
- TEST19.INP - Male speech, ambient noise, active speech level:
-36.0 dBov, modified IRS frequency response, with many zero frames.
