wavaug module

This module does multichannel audio flies augmentation.

wavaug.amp_args_validation(amplitude_list_str) → str

Function make external check of args for option dly.

wavaug.amplitude_hdr(args)

Function makes CLI amplitude augmentation.

wavaug.augmentate(args)

Augments the input audio file based on the provided arguments.

Parameters:

args (argparse.Namespace) – The command line arguments.

Returns:

None

Raises:

None –

This function performs the following steps:

  1. Calls the chain_hdr function to process the chain code from the arguments and execute the corresponding WaChain commands.

  2. Calls the input_path_hdr function to validate the input path.

  3. Calls the file_info_hdr function to retrieve information about the input file.

  4. Calls the output_path_hdr function to validate the output path.

  5. Calls the amplitude_hdr function to perform amplitude augmentation on the input file.

  6. Calls the noise_hdr function to perform noise augmentation on the input file.

  7. Calls the delay_hdr function to perform time delay augmentation on the input file.

  8. Calls the echo_hdr function to perform echo augmentation on the input file.

Note: This function does not return any value. It is expected to be called from the main function of the program.

wavaug.chain_hdr(args)

Processes the chain code from the given arguments and executes the corresponding WaChain commands.

Parameters:

args – The arguments containing the chain code to be executed.

Returns:

None

Raises:

  • SystemExit – Exits the program with a status code of 0 after

  • successful execution. –

wavaug.delay_args_validation(delay_list_str) → str

Function make external check of args for option dly.

wavaug.delay_hdr(args)

Function makes CLI delay augmentation.

wavaug.echo_args_validation(echo_list) → str

Function make external check of args for option echo.

wavaug.echo_hdr(args)

Function makes CLI echo augmentation.

wavaug.file_info(path: str) → dict

Returns a dictionary containing information about a WAV file.

Parameters:

path (str) – The path to the WAV file.

Returns:

A dictionary containing the following keys:

  • path (str): The path to the WAV file.

  • channels_count (int): The number of channels in the WAV file.

  • sample_rate (int): The sample rate of the WAV file.

  • length_s (float): The length of the WAV file in seconds.

Return type:

dict

wavaug.file_info_hdr(args)

Function prints info about input audio file.

wavaug.input_path_validation(in_path) → str

Function checks presence of input file

wavaug.is_file_creatable(fullpath: str) → bool

Checks if a file can be created at the given full path.

Parameters:

fullpath (str) – The full path where the file is to be created.

Returns:

True if the file can be created, False otherwise.

Return type:

bool

Raises:

  • Exception – If the file cannot be created.

  • SystemExit – If the path does not exist.

wavaug.main()

CLI arguments parsing.

wavaug.noise_args_validation(noise_list_str) → str

Function make external check of args for option noise.

wavaug.noise_hdr(args)

Function makes CLI noise augmentation.

wavaug.output_path_validation(out_path)

Function checks of output file name and path.

wavaug.parse_args()

CLI options parsing.

wavaug.print_help_and_info()

Function prints info about application

wavaug.validate_amp_list(amplitude_list: List[str]) → None

Checks if all elements in the given amplitudes list are valid numbers.

Parameters:

amplitude_list (list[str]) – The list of elements to check.

Returns:

None

Raises:

  • ValueError – If the list contains a non-number element.

  • SystemExit – Exits the program with a status code of 3 if a non-number

  • element is found. –

wavaug.validate_delay_list(delays_list: List[str]) → None

Checks if all elements in the given delays list are valid integers.

Parameters:

delays_list (list[str]) – The list of elements to check.

Returns:

None

Raises:

  • ValueError – If the list contains a non-integer element.

  • SystemExit – Exits the program with a status code of 1 if a non-integer

  • element is found. –
