pcm_mode | PCM byte encoding used. See constants below. | Read / Write | OGGVORBIS_PCM_S16_LE |
rate | PCM Sampling rate. Measured in Hz. | Write only | 44100 |
bitrate |
Vorbis Average Bitrate Encoding / Variable Bitrate Encoding.
Measured in bps (ABR) or Quality level (VBR: 0.0 to 1.0).
128000 ABR is rough equal to 0.4 VBR.
| Write only | 128000 |
channels | Number of PCM channels. 1 == Mono, 2 == Stereo. | Write only | 2 |
serialno |
Serial Number of stream within file. Must be unique within file.
Because of the potential to select a duplicate serial number within
a chained file, make efforts to manually assign unique numbers when
encoding.
| Write only | Random |
comments |
Associative array of file comments.
Will be translated to strtoupper($name) . "=$value".
Note: This context option is not available in oggvorbis-0.1
