I normally record at DAT quality, which is 48 Khz 16 Bit stereo.
Using wavrec I use the following syntax:
[dj@megajukebox]$ /usr/local/bin/wavrec −t 60 −s 48000 −S /mp3/temp.wav
The first part is an explicit path to wavrec. The '−t 60' specifies the length of time to record for, in seconds.
The third option, −s 48000 refers to the sample rate in samples/sec. (48000 is the rate for DAT, 44100 is CD)
The last option is the path to the output file.
To see the full set of options, run waverec −help, or see it's man page.
This will produce your WAV file Next you will need to encode it into MP3 format.
Use bladdenc with the following command line.
[dj@megajukebox]$ /usr/local/bin/bladeenc <em/[source file] [destination file]/ −br 256000
The −br option sets the bit rate, in this case I've set the rate to the maximum rate of 256k bits/s. The path to
bladeenc may also be different on your system to the one I've used in my example.
To see the full set of options, run bladeenc −help, actually this is an invalid option, but will display the list of
options.
The same encoding using Lame (as well as Gogo as it is based on Lame) would need the command line
[dj@megajukebox]$ /usr/local/bin/lame <em/[source file] [destination file]/ −b 256
10. Encoding from CD−ROM.
In a similar way to encoding from audio, encoding from CD is a 2 stage process. Firstly the audio data is
extracted from the cd and converted into a wav file. Then the wav file is converted into MP3.
There are basically 2 types of encoders, console based and X based. Both do the same job, but the X based
are easier to use (and look nicer).
Again, before you start to encode, check you will have enough drive space on your system.
