Because I fetched the .ogg file from and external MMC card, I can only red a limited memory block 1) Can I decode only a block of a speex file at time ? /*Create a new decoder state in narrowband mode*/ state = speex_decoder_init(&speex_nb_mode); /*Set the perceptu...

Dear Jan My intention is to read a piece at time of an .ogg file (stored in and external Multimedia card) decompress it and render it on and LPC2000 DAC. Because I don't have enough RAM memory to load the complete ogg file, I must read only a piece of file at certain time, then decompress and render it, and repeat the previous process until the end of the file. The problem is that I don't know what is the minimum file block size that I...
