What's new in QNX Software Development Platform 6.6 io-audio patch (patch ID 4687)

We've renamed the following:

Instead of using:	Use:
afm_vin_list_item_t	snd_afm_vin_list_item_t
afm_vin_pair_t	snd_afm_vin_pair_t
AFM_WAV_FILE	SND_AFM_WAV_FILE
snd_afm_service_get_audio_mode()	snd_afm_get_audio_mode()
snd_afm_service_get_vin_list()	snd_afm_get_vin_list()
snd_afm_service_get_vin_list_count()	snd_afm_get_vin_list_count()
snd_afm_service_set_audio_mode()	snd_afm_set_audio_mode()
snd_afm_service_set_path()	snd_afm_set_path()
snd_afm_service_set_vin_stream()	snd_afm_set_vin_stream()
snd_afm_service_start()	snd_afm_start()
snd_afm_service_stop()	snd_afm_stop()

The old functions call the new ones, but you should use the new names in your programs. We'll remove the old versions in a future release.

The following functions are new:

snd_afm_get_ap_data(): Retrieve data from the acoustic library in an AFM
snd_afm_load_ap_dataset(): Load an acoustic processing data set into a running AFM
snd_afm_set_ap_data(): Set data within the acoustic library in an AFM

Other changes include the following:

You can now enable a predictive limiter to reduce the distortion caused when audio data overflows.

If you specify an ampersand (&) before the key name in a configuration file, the value is appended to the key's current value.
The default value for config_write_delay is now -1, which prevents the settings from ever being written.
