Audio input compressed 'on-the-fly'?

Thymox · 03-24-2002, 10:53 AM

Is there a way to compress audio input directly into mp3/ogg files? I want to record some stuff from the radio late at night (using mix/aux in - no radio card in my box

) but don't want 2 or 3 hours of WAV file on my hd, hence was wondering about ogg compression 'on-the-fly' as it were.

Any ideas?

Cheers muchly.

ok ok... i've been fiddling with this for what.. 2 hours now i guess... and the only thing i've defintelly sussed out is that if you get sox from source, it can record to ogg from line-in. i've tried it, and it's absolutely crap quality, but i presume there's prolly a way to make it nicer.

there's record, part of xawtv, which record REALLY nicely with ncurses console gui to wav.

lame, which can encode FROM stdin, BUT i cna't find ANYTHING that will play from linein to stdout, as i guess it's a bit of a lame thing to want to do, even tho play, which IS the same program as rec DOES play to stdout... NRRG!

that doesn't do justice to my hours of research but hey... erm.. sod it.

This might take the thread way OT but doesn't voice over IP compress on the fly? OK so the quality is bad...

What do streaming servers (ie: RA) use for audio compression?

oh, knew i'd find the reason.. knackered sound cable! DOH!

Tried MusicMatch for Linux?

In windows it has a facility to perform on the fly Mp3 encoding with really good quality

Cheers guys. I tried using sox before, but it's the one that comes with Mandy. Will d/l the source later and try it. Might give that MusicMatch thing a go as well but... I've never been one of those people that is happy with a program that 'does it for you' - for example, I don't like (Windows) programs that rip cds and automagically give you the mp3 file - invariably they have the copy-protection bit set so although you can convert them back to wav, you can't burn them as audio cds. Sorry, bit of a ramble there, hey ho!

yeah, even the md82 version of sox doesn't have ogg support, i compiled from source, and it's all there, just make sure you specify -r 44101 on the rec cmd line, as that's all ogg can handle and it'll crash otherwise.

mmjb, yuck. i've only ever had hideous problems with that, it even uses it's own version of wine integrated into it.. yucky.
