create_audio_files()

audformat.testing.create_audio_files(db, *, sample_generator=None, sampling_rate=16000, channels=1, file_duration='60s')

Create audio files for a database.

By default, empty files are created. A sample generator function can be passed to generate the samples. The function gets as input a time stamp and should create a sample in the amplitude range [-1..1].

Parameters

• db (Database) – a database

• sample_generator (Optional[Callable[[float], float]]) – sample generator

• sampling_rate (int) – sampling rate in Hz

• channels (int) – number of channels

• file_duration (Union[str, Timedelta]) – file duration

Raises

• RuntimeError – if databases was not saved yet

• RuntimeError – if database is not portable
