Lavavo Settings Centre
This section describes the options that can be filled out
in the Lavavo Settings Centre.
Next, this section describes the settings for the encoders.
Bitrate Values and How to Interpret
Them (Back to top)
Almost all the encoders work with a bitrate parameter, with
this variable you can set the amount of "compression"
of the audio files.
The bitrate is a measure of the number of bits (or kilobits,
etc) that it takes represent one second of sound. A higher
bitrate results in better sound quality, since the encoder
retains more or the original sound wave information. The downside
of a higher bitrate is the increase in the file size. You
can calculate the output file size based on the bitrate as
follows:
OutputFileSize [kilobytes] = Bitrate [Kbits/s] * Song Duration
[sec] / 8 [bits-per-byte]
Thus a song with a play time of 3 minutes and 16 seconds,
compressed at 128 Kb/s will yield:
FileSize = 128 * (3*60 + 16) / 8 = 3136 kilobytes
If this song were recorded as a plain WAV file (at the usual
settings of 44.1 thousand samples per second, stereo, 16 bits
per channel), the file size would equal 44.1 * 2 [two channels]
* 2 [two bytes per sample] * (3*60+16) [seconds] = 34,574.4
kilobytes.
So the compression ratio in this example is 34,574.4 / 3136
= about eleven.
(The figures above are approximate, and don't take into account
a few bytes here and there for headers, ID3 tags, etc.)
A handy rule of thumb with 128Kbps compression is that it's
about "a meg a minute". (128 * 60 / 8 = 960KB, about
1MB)
Thread Priority (Back
to top)
This setting allows you to change the thread priority of
the encoder. Turning up the thread settings can reduce the
encoding time, at the expense of Windows becoming less responsive.
Output to RIFF-WAV File (Back
to top)
The output file is written as a RIFF-WAV file. This means
that there is stored an additional header ( a so-called RIFF-WAV
header ) at the beginning of the encoded file. Furthermore,
the extension becomes .WAV. If you have installed a Windows
Codec to decompress MP3 Files, this option might be useful.
Since Windows takes care of the decompression, even applications
that are not aware of the MP3 format can handle this file
format via the Windows Codec.
On-the-fly Encoding (Default Value
: ON) (Back to top)
When enabled, tracks are recorded directly into the desired
compressed format (e.g. MP3 / WMA / OGG) without having to
store the entire file first to a WAV file. However, with some
configuration people have heard strange clicks in the output
file. Therefore, if this option is off, the file is first
record as a WAV file, which can be converted to the desired
output format. The WAV file is automatically deleted when
the conversion has been completed.
DISABLE THIS OPTION IF YOU EXPERIENCE STRANGE CLICKS IN
YOUR MP3 FILES.
