Hola a todo el foro:
Me gustaria saber si hay algun capturador de sonido para linux, es decir, que yo enchufe un cable por la entrada de sonido de la tarjeta de sonido, y que lo pueda grabar en el pc, a ser posible en mp3 o si no es posible pues en wav. Si no sabeis a lo que me refiero, en hasefroch uso en Sonetics X-Ripper. Los uso para grabar de la radio un programa los lunes, y me gustaria no tener ke abrir hase todos los lunes. Agur y gracias por adelantado!!!
Si usas los drivers OSS se puede hacer con sox. Para que sea mp3, wav, ogg o el formato que se te antoje, basta una tubería.
Aquí explican cómo hacerlo:

Yo lo probé en su tiempo (precisamente para grabar radio) y me funcionaba.
Si tienes alsa, supongo que funcionará igualmente si está cargado el módulo ese para emular al driver oss. Quizás también valga "arecord" escuchando /dev/dsp, pero no tengo tiempo de investigar.
EDITO: Quizás sea más "pofesional" esta utilidad, aunque para la radio debe bastar y sobrar con lo anterior:

Description: Transfer sound from gramophone records to CD
GramoFile enables you to record audio from (for example) gramophone
records, process the signal and listen to the results. Because sound
files in .WAV-format are used, it is possible to exchange the files
with many other programs. Cdrecord(1) can burn CD-Recordables of these,
so you can make CDs with the music of your favorite records. The user
interface of GramoFile has a windows-like look-and-feel, making it
fairly easy to use.
.
One of the most important parts of GramoFile is the ability to process
digital audio signals. Through the application of several filters it
is possible to accomplish a significant reduction of disturbances like
ticks and scratches. These filters have been programmed in such a fashion
that they can be applied in any order (and multiple times) in a single
run, thus avoiding the use of temporary files. It is possible to adjust
the properties of each filter independently, so in every situation an
optimal result can be achieved.
.
Another interesting feature is the track splitting. Just make one .wav
file of an entire side of an record and GramoFile will detect where
the individual tracks are located. This happens fully automatically,
without need to set any options. More experienced users may fine-tune
the algorithm, or change the detected track starts and ends, but
generally that will not be necessary. Track-times are saved in an
editable (plaintext) .tracks file, that will be used during the signal
processing to produce one processed .wav file for each individual track.
.
To record and play .wav files, modified versions of brec(1) and bplay(1)
by David Monro are included. These programs provide buffered recording
and playback, so all will go well even on a highly loaded system. Both
programs have been modified to support the standard GramoFile user
interface. Brec also got a `graphical' peak level meter, and bplay a
running time display.
