Opaque container for audio conversion options.
You don't want to know what's inside.
Dither mode.
| enum gavl_resample_mode_t |
Resample mode.
| GAVL_PUBLIC void gavl_audio_options_set_quality | ( | gavl_audio_options_t * | opt, |
| int | quality | ||
| ) |
Set the quality level for the converter.
| opt | Audio options |
| quality | Quality level (see Quality settings) |
| GAVL_PUBLIC int gavl_audio_options_get_quality | ( | const gavl_audio_options_t * | opt | ) |
Get the quality level for a converter.
| opt | Audio options |
| GAVL_PUBLIC void gavl_audio_options_set_dither_mode | ( | gavl_audio_options_t * | opt, |
| gavl_audio_dither_mode_t | mode | ||
| ) |
Set the dither mode for the converter.
| opt | Audio options |
| mode | A dither mode |
| GAVL_PUBLIC gavl_audio_dither_mode_t gavl_audio_options_get_dither_mode | ( | const gavl_audio_options_t * | opt | ) |
Get the dither mode for the converter.
| opt | Audio options |
| GAVL_PUBLIC void gavl_audio_options_set_resample_mode | ( | gavl_audio_options_t * | opt, |
| gavl_resample_mode_t | mode | ||
| ) |
Set the resample mode for the converter.
| opt | Audio options |
| mode | A resample mode |
| GAVL_PUBLIC gavl_resample_mode_t gavl_audio_options_get_resample_mode | ( | const gavl_audio_options_t * | opt | ) |
Get the resample mode for the converter.
| opt | Audio options |
| GAVL_PUBLIC void gavl_audio_options_set_conversion_flags | ( | gavl_audio_options_t * | opt, |
| int | flags | ||
| ) |
Set the conversion flags.
| opt | Audio options |
| flags | Flags (see Audio conversion flags) |
| GAVL_PUBLIC int gavl_audio_options_get_conversion_flags | ( | const gavl_audio_options_t * | opt | ) |
| GAVL_PUBLIC void gavl_audio_options_set_defaults | ( | gavl_audio_options_t * | opt | ) |
Set all options to their defaults.
| opt | Audio options |
| GAVL_PUBLIC void gavl_audio_options_set_mix_matrix | ( | gavl_audio_options_t * | opt, |
| const double ** | matrix | ||
| ) |
Set a user defined mix matrix.
| opt | Audio options |
| matrix | Mix matrix to use |
The matrix consists of coefficients, where matrix[i][j] is the factor for mixing input channel j to output channel i. The matrix is not copied, so it should be valid at least until the next call to gavl_audio_converter_init.
To clear a previously defined mix matrix (restoring gavls default behaviour) pass NULL.
Since 1.1.2
| GAVL_PUBLIC const double** gavl_audio_options_get_mix_matrix | ( | const gavl_audio_options_t * | opt | ) |
Get the mix matrix.
| opt | Audio options |
Since 1.1.2
| GAVL_PUBLIC gavl_audio_options_t* gavl_audio_options_create | ( | ) |
Create an options container.
Use this to store options, which will apply for more than one converter instance. Applying the options will be done by gavl_*_get_options() followed by gavl_audio_options_copy().
| GAVL_PUBLIC void gavl_audio_options_copy | ( | gavl_audio_options_t * | dst, |
| const gavl_audio_options_t * | src | ||
| ) |
Copy audio options.
| dst | Destination |
| src | Source |
| GAVL_PUBLIC void gavl_audio_options_destroy | ( | gavl_audio_options_t * | opt | ) |
Destroy audio options.
| opt | Audio options |
