<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.
