 To make some test recordings we first create a new project. Start Traverso and 
select ``New\dots''. Enter a name, set the number of sheets to 1, the number of 
tracks to 2, and leave the rest empty. Then press ``OK'' to create the project 
and show it's first sheet. Note: All recorded audio data will be stored in 
\texttt{project\_dir/project\_name/audiosources}, so if you followed our advice 
and selected a project directory on a pratition with lots of free space, you 
shouldn't run out of disk space now.
 
 \section{Setting up the driver}
-To set up the driver backend, open the preferences dialog by clicking 
``Settings $\rightarrow$ Preferences\dots'' (\FigB\ \ref{fig_driversettings}). 
Which driver is appropriate for your system is described in chapter 
\ref{sect_setup}. In the driver configuration one can chose the sampling rate, 
and Traverso always uses the sampling rate of the driver backend for its 
recordings. Traverso's audio engine works entirely in 32 bit floating point 
precision, and you can chose from the menu ,,Settings $\rightarrow$ Recording 
file format'' whether the data should be stored in a standard Wave format, in 
Wave-64, or in FLAC. The bit resolution will always be 32~bit floating point.

 Port audio is the recommended driver backend on Mac OS X and Microsoft 
Windows. It connects to the system's native sound system (CoreAudio on OS X, 
WMME on Windows). Simply select ``PortAudio'' in the driver configuration 
widget, the samplerate you wish to use, and a latency that works for you.
 
 \section{Recording file format}
-From the menu ,,Settings $\rightarrow$ Recording file format'' you can set the 
file format used for recorded audio. \emph{Wave} has been the standard audio 
format in the computer world for years. It is uncompressed, and Traverso stores 
all audio data in 32~bit floating point precision, no matter what bit depth the 
driver backend was set to. Wave files, however, are limited to a size of 2~GB. 
For a mono recording in 44100~Hz 32~bit resolution this gives a maximum 
recording time of approximately 3 hours and 20 minutes. For a stereo recording 
it is only half of that time. If you plan to record longer you should use the 
\emph{Wave-64} format instead, which can write much larger files. The third 
format, \emph{WavPack}, uses a lossless compression algorithm to shrink your 
files without affecting the quality of the audio data. However, since the 
encoding is done in real time, more CPU power is required while recording. If 
you are short of disk space but have a decent CPU, this format is certainly a 
good choice.
