Number from -1 to 10 -1 is the highest compression VBR encoding with quality factor such as -4.2.

If the input file has integer wav format and normalization is off, then it has Providing the argument might help when libsox can not infer the format įormat ( str or None, optional) – Override the format detection with the given format. Otherwise, the returned Tensor’s dimension is. This argument has no effect for formats other than integer WAV type.Ĭhannels_first ( bool, optional) – When True, the returned Tensor has dimension. If input file is integer WAV, giving False will change the resulting Tensor type to Normalize ( bool, optional) – When True, this function always return float32, and sample values are

This function may return the less number of frames if there is not enough Num_frames ( int, optional) – Maximum number of frames to read. Note: This argument is intentionally annotated as str only due toįrame_offset ( int) – Number of frames to skip before start reading data. When the function is compiled by TorchScript, only str type is allowed. Which returns byte string of at most size length. ), the following types are accepted įile-like: Object with read(size: int) -> bytes method, When the function is not compiled by TorchScript, Normalize parameter has no effect on 32-bit floating-point WAV and other formats, such asįor these formats, this function always returns float32 Tensor with values normalized toįilepath ( path-like object or file-like object) –

Support int24 dtype, 24-bit signed PCM are converted to int32 tensors. Int16 for 16-bit signed PCM and uint8 for 8-bit unsigned PCM. Of the corresponding dtype, that is, int32 tensor for 32-bit signed PCM, This function can return integer Tensor, where the samples are expressed within the whole range Signed integer, 24-bit signed integer, and 8-bit unsigned integer, by providing normalize=False, When the input format is WAV with integer type, such as 32-bit signed integer, 16-bit The samples are normalized to fit in the range of. Handle natively, your installation of torchaudio has to be linked to libsoxĪnd corresponding codec libraries such as libmad or libmp3lame etc.īy default ( normalize=True, channels_first=True), this function returns Tensor withįloat32 dtype and the shape of.
