|
|
<P>
|
|
The publically callable functions of libsamplerate are all listed in the
|
|
<B><samplerate.h></B> header file.
|
|
In order to use any of the functionality of libsamplerate, you need to add
|
|
</P>
|
|
<PRE>
|
|
#include <samplerate.h>
|
|
</PRE>
|
|
<P>
|
|
to the top of any function that call any of the following functions.
|
|
You will also need to link you binary with the libsamplerate library.
|
|
</P>
|
|
<P>
|
|
The API allows three methods for accessing the capabilies of the library:
|
|
</P>
|
|
<UL>
|
|
<LI>A <A HREF="api_simple.html">simple interface</A> which can sample rate convert
|
|
a single block of samples (one or more channels) in one go.
|
|
The simple API is less capable than the full API.
|
|
<LI>A <A HREF="api_full.html">more fully featured interface</A> which allows time
|
|
varying sample rate conversion on streaming data (again one or more
|
|
channels).
|
|
<LI>A <A HREF="api_callback.html">callback interface</A> which has the same
|
|
functionality as the interface above but allows the details of input and
|
|
output to be separated.
|
|
The output is generated by call a read function and the library calls a user
|
|
supplied callback function to obtain its input.
|
|
This interface is particularly well suited to applications where the output
|
|
sample rate is varied with time.
|
|
</UL>
|
|
|
|
<P>
|
|
<b>NB :</b> All three access methods are able to process multi channel interleaved
|
|
data.
|
|
</P>
|
|
|
|
<P>
|
|
The parts of the API which are common to all three interfaces are:
|
|
</P>
|
|
<UL>
|
|
<LI> The <A HREF="api_misc.html#ErrorReporting">error reporting</A> mechanisim.
|
|
<LI> The available <A HREF="api_misc.html#Converters">converter</A> types.
|
|
<LI> The <A HREF="api_misc.html#SRC_DATA">SRC_DATA</A> struct.
|
|
</UL>
|
|
<P>
|
|
All three versions of the API are restricted to operating on buffers of ISO C
|
|
Standard <B>float</B> data.
|
|
However, there are two
|
|
<A HREF="api_misc.html#Aux">auxillary functions</A>
|
|
for converting arrays of float data to and from short data.
|
|
</P>
|
|
|
|
<P>
|
|
<B>Note:</B> The <B>tests/</B> and <B>examples/</B> directories of the source code
|
|
distribution contain numerous example programs showing the use of the library.
|
|
