Description

WAV file interface module.

This interface module is narrowly focused to read a common wav file format and send the data samples to mapping modules.

Interface module configuration parameters

Name	Description
intf_nv_file_name	Name of the file to be read
intf_nv_file_name_rx	Name of wav file where received data will be stored
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
intf_nv_number_of_data_bytes	Size of sample data counted in bytes. This size should be equal to Subchunk2Size field in wav file to be transferred. The data is printed out by talker when started (INFO: Number of data bytes)

There are some parameters that have to be set during configuration of this interface module and before configuring mapping:

These parameters can be set in either:

in the ini file (or available configuration system), so values will be parsed in the intf_cfg_cb function,
in the interface module initialization function where valid values can be assigned directly

Values assigned in the intf_cfg_cb function will override any values set in the initialization function.
