Hi Pete,
I'm sorry, the *.wav format doesn't match the 56k data format.
1.) it's either 16bit or 32bit (basically this is no problem to match the
word length)
2.) it's Intel little endian format
3.) The header should thrown away since it is ont of any use for the DSP.
4.) the DSP RAM is to small to record more than some seconds of audio - the DSP
is designed for real time audio processing, not for audio recording.
Anyway, you can record raw PCM data using the DSP. Simply play back the *.wav
file by an audio device and connect the DSP board to it. Write an application
that increments a pointer to the next memory cell after writing a sample.
It' that easy. It can do stereo using the x: and y: memories.
move #xybase,r0 ;define xybase for unused memory
move x:RX_BUFF_BASE,a ;receive left
move x:RX_BUFF_BASE+1,b ;receive right
move a,x:(r0)+
move b,y:(r0)+
Best regards

Does anyone know of any documentation regarding downloading wavs or aiffs down
to either DSPX72YDBZE 56720 Dev Boards external ram or SPI/I2C eprom (and then
copying it in) using symphony studio.
