Higher sample rates like 96kHz can be useful in sound design applications where you would like
flexibility to apply extreme pitch adjustments to the recording. A sound recorded at 96kHz and played
at half-speed would still be able to reproduce frequencies up to 24kHz, while the same sound recorded
at 48kHz and played at half speed will only be able to reproduce frequencies up to 12kHz.
8.3. Buffer Size
Buffer size is expressed in samples and is usually found in your application's audio settings.
Think of the buffer like a bucket. As soon as it fills up with samples, it is carried away to
the output. So, the smaller the bucket (buffer) the quicker it will get filled up and sent to the
output, and therefore will play back with less latency. The tradeoff, however, is that smaller
buffer sizes require your computer's CPU to work harder. Conversely, the bigger the bucket
(buffer) the longer it will take to fill up and be sent to the output. This decreases the load on
your CPU at the expense of more latency. As you will see below, changing the buffer size
depending on the type of audio task being performed is common practice.
If you experience clicks and pops in your projects, try increasing the buffer size in your host
application or the audio driver.
