NAME

SDL2::AudioCVT - The Structure that Holds a Set of Audio Conversion Filters

SYNOPSIS

use SDL2 qw[:all];
# TODO: I need to whip up a quick example

DESCRIPTION

SDL2::AudioCVT is a structure to hold a set of audio conversion filters and buffers.

Note that various parts of the conversion pipeline can take advantage of SIMD operations (like SSE2, for example). SDL2::AudioCVT doesn't require you to pass it aligned data, but can possibly run much faster if you set both its (buf) field to a pointer that is aligned to 16 bytes, and its (len) field to something that's a multiple of 16, if possible.

Fields

needed - Set to 1 if conversion possible

src_format - Source audio format

dst_format - Target audio format

rate_incr - Rate conversion increment

buf - Buffer to hold entire audio data

len - Length of original audio buffer

len_cvt - Length of converted audio buffer

len_mult - Buffer must be len * len_mult big

len_ratio - Given len, final size is len * len_ratio

filters - List of filter functions

filter_index - Current audio conversion function
