The Advanced Linux Sound Architecture (ALSA) - utilities
4ab7510f3a
This commit adds support for data of Creative Tech. voice format. In this data format, values in each of field are represented in little-endian byte order and available formats of data sample are restricted in little-endian byte order. In version 1.10 of this format, sampling rate is represented with reciprocal number of the rate, thus we cannot calculate original sampling rate precisely just from its header. For example at 44.1kHz, file header includes 233 (=256-1,000,000/44,100), but we cannot recover the value just from the code (43478.2...). For my convenience, this commit adds a pre-computed table and lookup major rates from the table. Additionally, this format can includes several blocks with different sample format. When handling this type of file, we need to start/stop substream for each of the block, while this brings complicated code. This type of format is enough ancient and presently quite minor. This commit takes a compromise and handles a first sample block only. Signed-off-by: Takashi Sakamoto <o-takashi@sakamocchi.jp> Signed-off-by: Takashi Iwai <tiwai@suse.de> |
