XAudio2 Sample Rate Conversions - Win32 apps | …

Sample rate conversion processing only occurs when necessary. Converting audio data to a different sample rate incurs more processing overhead, which it is preferable to avoid. If a voice's input sample rate matches the input sample rate of its output voices, this conversion is not done and processing time is shortened.
Sample Rate Conversion - PS Audio

Based on those two things, we can derive a commonly-quoted requirement that in order to achieve high quality, digital audio must therefore have a sample rate of at least 40kHz. For those reasons, the standard sample rate which has been chosen for CD audio, and widely adopted for digital audio in general, is 44.1kHz.

https://github.com/zephray/SampleRateConverter
This is a C implementation of an audio sample rate convertor based on Polyphase FIR filter. It can be used to up or downconverting the sample rate of a raw audio stream with any fractional ratio. However this may not suitable as an arbitrary resampler as memory space consumption goes up linearly as the numerator of the ratio goes up. The stream should be in …

Sample rate conversion (SRC) is the process of changing the sampling rate of a data stream from a specific sampling rate (e.g. the input/output hardware rate) to another sampling rate (e.g. the application rate).

This is libsamplerate, 0.2.2. libsamplerate (also known as Secret Rabbit Code) is a library for performing sample rate conversion of audio data. The src/ directory contains the source code for library itself. The docs/ directory contains the libsamplerate documentation. The examples/ directory contains examples of how to write code using libsamplerate.

I am about to write an audio file converter for my side job at the university. As part of this I would need sample rate conversion. However, my professor said that it would be pretty hard to write a sample rate converter that was both of good quality and fast.. On my research on the subject, I found some functions in the OSX CoreAudio-framework, that could do a sample …

The most common audio sample rate you’ll see is 44.1 kHz, or 44,100 samples per second. This is the standard for most consumer audio, used for formats like CDs. This is not an arbitrary number. Humans can hear frequencies between 20 Hz and 20 kHz.
