RE: Play wav files from serial input
Why == because we want to have an 8 button keypad in engineers cubes where when you press a button a .wav (or .mp3) from a corresponding category is played through the overhead speakers. Have you ever heard the joke about all the regular blokes in a bar where they don't actually tell complete jokes anymore, they just shout out a number like 73 and then everyone laughs? We have a number of sound files and clips that have to me (gasp) manually played back from individual machines by clicking on them. It would be more efficient to be able to just press a button and have an appropriate sound/noise/audio clip come through the overhead speakers. Thanks for the play tip, I found a reference to that via google and looks good for playing .wav's. I imagine there is a similar one for .mp3's, or I can just require people to convert them... -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Bill Freeman Sent: Wednesday, January 12, 2005 2:44 PM To: Brian Cc: 'GNHLUG' Subject: Play wav files from serial input Brian writes: Setup a linux server with a samba share and directories labelled 1-8. .wav files can be put in those dirs and when a simple serial string is received a random file is selected from the appropriate directory and played via the line-out of the sound card. Ok, but why. Any suggestions for a good command-line capable .wav player? Try play.

That's been standard in RedHat and derivatives for a while, and I assume in other distributions as well. I'm running Fedora Core 2, and play comes from sox-12.17.4-4.fc2 there. The sox documentation is extensive, and I believe that it can deal with a number of formats. I'm not sure about mp3, however. Don't those need closed source codecs? Someone will tell us. Now if only I could get the shound inputs on the ASUS mother board to work. (I'd been happily converting records to digital until my laptop died last year.)

Not sure about what play does, but mpg123 is what I use as my actual mp3 player, so I suspect it will do the job ;) -- Christopher Schmidt pgpIBHBrIzNwj.pgp Description: PGP signature

Ripping a CD is child's play. An all digital operation, it doesn't even require a sound card. My LPs, 45s, and 78s won't fit in the CD drive, however. Digitizing from an analog source is generally a realtime only operation. You might think that you could save some time by playing the LPs at 45 and setting the sampling rate a 1.35 times the desired rate, but then the equalization filter in the phono pre-amp wouldn't match the pre-emphasis on the record. Maybe you could convert those 3.75ips tapes at 7.5 ips, though. Set the quality levels in your convert utility as high as you can. that way you won't have to rip any CD's over again. (My Linda Ronstadt albums had lot's o' dropouts, dunno why. ) (Linda who? :-) ) She's the one that did that album with Nelson Riddle, isn't she?

Of course I bought CD's of every analog item I had, and stored the original true analog media away in a safe place, knowing that it actually held all the music, and not just some arbitrary slices of the music.. :-) And I've never touched them again.

I use Audacity for this; it's versatile, has a nice GUI, and you can save your recording as a project (for me, that's usually an entire album, with recording having been paused while I flipped it over) in Audacity's native format. Whether saved or not, one can then easily export selections from that project into the individual wav/mp3/ogg files corresponding to each track, optionally adding mp3id info. It pays to have reasonable acreage to work with on disk, of course, especially if you plan on doing multiple editing operations on the entire project. Note that you'll need to have the appropriate libraries installed to be able to use the mp3 and ogg formats - liblame libvorbis, IIRC - and there's some other lib for mp3id support. Some distributions have made the lame lib (and its variants) a wee bit more difficult to locate and install than others ones have ... or so I gather from the folks (the lamers?) that will even admit to using that sort of thing. *cough* ;) -- Bill Mullen RLU# 270075 ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss
