5.1
What do I need to compile Kwave?
Read in the
chapter
mentioned before. It compiles with
gcc and egcs as well.
5.2
Which sound cards does Kwave support?
Kwave does not need support for any special sound card.
The sound card only has to be supported by your
operating system and Kwave uses it's interface to the
operating system's sound driver through a standard
interface. So Kwave can play on any sound card that
KDE is able to play on.
5.3
Why are some menu entries / features always disabled?
This is just because we decided that those actions
are not working stable enough to present them to
the normal user and therefore disabled them to
avoid trouble. You will get access to them if they
are tested and stable enough.
5.4
Why does Kwave consume more memory than it can be
expected from the size of the opened file?
The reason for this is that Kwave internally stores
all samples in 32-bit integers. This was easy to program,
made the application faster and a bit more reliable.
So if you load an 8-bit file with about one megabyte
it will consume about four megabytes.
Maybe we will change this somewhere in the future...
5.5
Which sound formats does Kwave support?
Kwave currently supports .wav files with 8, 16 and
24 bits per sample, with any number of channels
(of course including mono and stereo).
5.6
What if I have files with a format not
supported by Kwave?
If you have to work on an other format, you can convert
it into .wav format. A good set of tools for this is
in the
SoX package, they have also some nice
documentation!
5.7
I get errors when I want to do playback?
Maybe you have choosen a combination of playback
rate and sample size that is not supported by your
sound driver and / or sound hardware. Try playback with
8 bits per sample and mono first, this should always
work. Then try to increase the bits per sample and
stereo playback step by step. Note that some playback
rates are not at all supported by some sound hardware.
5.8
The playback seems to do something but I hear nothing?
Maybe you have forgotten to increase the volume of
the playback channel. Kwave is not responsible for
changing the playback volume.
5.9
Some files are played with half-speed?
Try choosing a different sound playback device.
5.10
The playback sometimes is disturbed and interrupted?
You should increase the size of the playback buffer
to get a "smoother" playback (this also makes the
playback control reacting a bit slower).
5.11
The playback does not stop if I immediately
press the stop button?
The reason for this is that the sound driver already
has received some playback data from Kwave at the
moment when you press the stop button. Decrease the
size of the playback buffer and it should react faster
(but makes interruptions more probable).
Sorry, currently we don't have direct support for ALSA, but
since version 0.6 Kwave has support
for aRts,
which can use ALSA.
5.13
What about playback with 24 and 32 bits per sample
or more than two channels?
This is another feature that might get implemented
in aRts,
so we wait for aRts to support it.
5.14
What about MP3 support?
Not for the moment, but maybe someone writes us
a plugin for MP3 import / export?
