best sound format and app. for recording voice.
Quoted 11 lines · Bryan Bolden
I am in school and I tape my classes. what I would like to do is to begin to keep digital copies of the taped classes on my computer without taking up so much disk space. what I will do is have the output jack of the tape recorder connected to the input jack of my sound card. I need to know the best sound format and a good (maybe free but I am open to buying a good app) application that will allow me to make digital samples with mono recording and at least radio quality that will not take up a lot of space for a taped class of about an hour.
I would prefer the application run on linux but I am open to a good M$ windows based sound application (please forgive me but I am desperate :)
vor pure voice it's enough to use bitrates lower that 32kbit/sec
I think Realaudio isn't that bad for this purpose (windows and linux encoder exists).
for example the 16kbit codec uses 2kbytes/sec the 24kbit coded 3kbytes/sec
that means 1hour of realaudio at 24kbit = 3kbyte/sec*3600secs = 11MBytes
A 10GB disk can hold 1000 hours or speech , that is 500-1000 tapes.
John as you see compressed audio on disk isn't more expensive than tapes.
a 10GB disk costs almost nothing these days
:-)
PS: IBM just rolling out 75GB (!) 3 1/2 inch SCSI disks , EIDE versions will follow soon. (I think in the 50GB area but dirty cheap :-) )

Yea, I was thinking D to D. Digidesign (studio quality) which was all i knew at the time and I've been out of it for 5 years.
Shoulda waited before I opened my mouth, I keep forgetting that one of the reasons I got outta the business was that recording equipment was becoming dirt-cheap.

Arg, I think I am wrong,
I heard about Realserver for Linux, but I am not sure if it includes an encoder. Anyway I try to avoid proprietary codecs.
( Realnetworks still not able to deliver a decent realplayer for linux, my guess is that if they do not open their protocols , Microsoft will kill them just like they did with Nescape
.. hopefully there will be a Mozilla-of-the-streaming-protocols :-) )
But as Artur pointed out, GSM isn't that bad at 12kbit/sec, plu when searching around the net I found a voice coder which runs at about 4.8kbit/sec .
or if you want extreme low bit rates use the LPC-10 code , down to 2.4kbit/sec, = 1.1MB/hour :-)
But I don't know if the quality high enough for you

no, you're not wrong. I had realproducer on my box a while back before a recent cleanup. Not sure where it is on their site now.

I know I'm starting to get a bit off-topic with this question, but...
I'm able to get the codecs for xanim to show me .avi files, but .mpg's play dreadfully. Can anyone point me in the right direction as to how to get these to work as they should?
Thanks. (Private email reply preferred... unless of course if it would interest others here).
Cheers
Tony
oh good grief.
well that might work over a 2400 modem.
I remember a Linux encoder from long ago, I still have the files if there's interest. Microsoft has not seemed interested in providing a product for Linux, their mediaplayer doesn't work for Linux, forcing us to use mp3 to encode our audio.

It's interesting to see, what RealNetworks is going to do in the near future. IMHO RN should open-source all their players and encoders, and for all platforms. And they should do it now. This would have quite an impact. As mp3 suffers from licensing problems, many people would prefer a GPL'ed RA-de/encoder. Let's hope this happens.

Yep, there are plenty of encoders out there, but when distributing your music (or some other "popular" activity), ease of use and availability are crucial. And RealAudio is easy to use and it is widely spread.

I wouldn't be a Realnetworks shareholder right now ... :-)
they still think that they can fight M$ but with proprietary models this will just not work.
Did you notice that they pulled Realaduio support from the latest mediaplayer ? Why ? , simple: to force users to use MS-Audio.
Because Joe Average is too lazy (or too dumb :-) ) to download the RA Player. :-)
If Realnetworks doesn't react right now, (opensourcing codecs would give them a big boost in terms of acceptance).
It could easy happen that Linux will save their a** because the level playing field of Linux.
But if we wait too much, all streaming sites will only run MS-Audio , and M$ will be able to control the entire streming arena.
( with the advent of broadband , streaming will be a big $$$ business, and M$ wants all of the pie)

Agreed, but in this case the user wanted only to store his voice recordings on his own disk, therefore a special codec would be appropriate.
