|
<p>Functions to convert between NumPy arrays and Sound objects. This
|
|
module will only be functional when pygame can use the external NumPy
|
|
package. If NumPy can't be imported, <code class="docutils literal notranslate"><span class="pre">surfarray</span></code> becomes a <code class="docutils literal notranslate"><span class="pre">MissingModule</span></code>
|
|
object.</p>
|
|
<p>Sound data is made of thousands of samples per second, and each sample is the
|
|
amplitude of the wave at a particular moment in time. For example, in 22-kHz
|
|
format, element number 5 of the array is the amplitude of the wave after
|
|
5/22000 seconds.</p>
|
|
<p>The arrays are indexed by the <code class="docutils literal notranslate"><span class="pre">X</span></code> axis first, followed by the <code class="docutils literal notranslate"><span class="pre">Y</span></code> axis.
|
|
Each sample is an 8-bit or 16-bit integer, depending on the data format. A
|
|
stereo sound file has two values per sample, while a mono sound file only has
|
|
one.</p>
