Should'nt be a problem to +record huge files. Well, unless you run out of memory... +<p> +Recording and playback is basically finished, fine-tuned and debugged for +Linux/i386 systems now. There are some i18n and portability issues. +Other OSS/little-endian boxes should work fine too (but this is untested), +OSS/big-endian should work with 8-bit sound. +<p> +I dropped my plans to add more functions and entered the +BugfixingAndMaintaining Mode. For editing check out the other +programs, there is kwav for example. + +<h3>Description</h3> + +mostly TODO, currently only the most important stuff is listed. +<p> +The main part of the window is just a list of the buffers you have. +Empty after startup. krecord knows two sorts of buffers: +<dl> +<dt>memory buffers +<dd>these are kept in memory, if you want to keep the data there, you +have to save the buffer to a file. +These are listed as "buffer #nr". +<dt>file buffers +<dd>these are attached to a file and krecord reads and writes directly +from/to the file. These are listed with the filename. +</dl> +File buffers are useful if you want to record huge sound files (with size > +RAM). But they are more sensitive to background activity, +i.e. recording overruns are more likely. +<p> +recording/playback starts allways at the beginning of the +buffer, there is no position scale. +<p> +The status line holds (from left to right): status / sample rate / +channels / audio format / latency. status might be: +<dl compact> +<dt>idle +<dt>playback +<dt>recording +<dd>I think these are clear... +<dt>monitor +<dd>reads data from the souncard and processes them. You can use the +freq spectrum window or input level window (or both :-) to see what +comes in. You can adjust the record level then. It is nice for +trouble-shooting too. If no data arrives, you probably have to set +the right recording source with a mixer program, kmix for example. +There is a menu entry in the options menu to start up kmix... +<dt>waiting +<dd>krecord waits for a signal higher than the record trigger level. +record trigger level is specified in percent. 5% gives good results +most of the time for me, but YMMV depending on quality and volume of +the input signal. +</dl> +<p> +The freq spectrum displays the frequencies from 100Hz to 10kHz. The +x-axis has a logaritmic scale - 1kHz is in the middle. y-axis is +linear, the horizontal red line ist the maximum level. +<p> +There are a few handy keyboard shortcuts: +<dl compact> +<dt>up/down +<dd>walk in the buffer list +<dt>Return +<dd>start playback +<dt>'R' +<dd>start recording +<dt>Escape +<dd>stop record/playback +<dt>'N', Space +<dd>starts a new file buffer (named song<nr>.wav). This +is useful for recording your old LP's (if you want to burn them to +CD's): Just start krecord, your LP, and press 'N' every time you want +to start a new track. Burn with "<tt>cdrecord -audio +song*.wav</tt>". +</dl> + +<h3>Known Problems</h3> + +<ul> +<li>I have trouble with recording overruns sometimes :-( +<li>The freq spectrum/input level is'nt in sync for playback - it +does'nt take in account the delay due to the sound driver buffering. +<li>Supports OSS only. Yes, there already is a sunaudio.cpp file, but +this is currently a dummy only...<br> +support for big-endian machines needs some work too. +</ul> + +<h3>TODO List</h3> + +<ul> +<li>more i18n +<li>portability +</ul> + +<h3>Credits</h3> + +<ul> +<li>Florian Kolbe <Florian.Kolbe@in-gmbh.de> (input level window) +<li>Stéphane Gourichon <gouricho@poleia.lip6.fr> (input level patches) +<li>Thomas Strehl <tstrehl@suse.de> (KDE2 port) +</ul> + +<hr noshade> +<address>Gerd Knorr +<<a href="mailto:kraxel@goldbach.in-berlin.de">kraxel@goldbach.in-berlin.de</a>> +</address> +</body> +</html> |
