Description

This interface module is a talker only and is used to generate an audio tone for testing purposes. It is designed to work with the AAF (AVTP Audio Format) mapping but could be quickly adjusted to work with the 61883-6 mapping module as well.

Interface module configuration parameters

Name	Description
intf_nv_tone_hz	The frequency of the generated tone
intf_nv_on_off_interval_msec	How many millisecs to turn on and off the tone
intf_nv_melody_string	A simple melody to play. When a melody string is set the on/off tone hz is not used.

intf_nv_audio_rate	Audio rate, numberic values defined by avb_audio_rate_t
intf_nv_audio_bit_depth	Bit depth of audio, numeric values defined by avb_audio_bit_depth_t
intf_nv_audio_channels	Number of audio channels, numeric values should be within range of values in avb_audio_channels_t
