[linux-audio-user] alsa-lib high level interface

by Burkhard Ritter

Hello. This is probably a bit off-topic. Anyway, I just wanted to write a simple alsa mixer app (for learning purposes) and wondered if there is some kind of a high level alsa-lib interface, as it seems to me quite 'deep down'. The documentation isn't too good either. As I am completely new to this stuff, I would greatly appreciate any help. Thanks. Burkhard

RE: [linux-audio-user] Noise removal, what filter is best?

by Reuben Martin

If it's a high pitch and confined to a relatively small bandwidth like I think you're describing, you could probably remove it with a notch filter pretty easily. You may want to start by looking at Freaqtweak. -Reuben -----Original Message----- From: Tim Beauregard [mailto:helycos@lycos.co.uk] Sent: Monday, August 25, 2003 4:18 PM To: linux-audio-user(a)music.columbia.edu Subject: [linux-audio-user] Noise removal, what filter is best? -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, I'm looking for a filter/software to remove noise from a sound file. I'm not an audio expert so will try to describe the noise in a way that you out there might be able to put a name to it and recommend a suitable filter/software to remove it. It is a short sharp blip, fairly high frequency, sounds like a compass point stabbing glass. It occurs as often as every minute or so in the two hour sound file. I obtained this file by recording DAB radio here in the UK. I'm presuming the noise is derived from errors in the transmission or analogue to digital conversion phase of the broadcast. I think it is due to a signal exceeding line volume. I've tried the gramofile filter 'Conditional Median Filter II', which failed to remove the noise. If necessary I could email a sample of the noise. I'm using Debian 3.0r0, 2.4.18 kernel. Thank you in advance :-) Tim Beauregard -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.0.6 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQE/Snz3sUUdIDHrdAURAuF/AJ9+QZHf4lZMgDLkAm+wv1Ov3dTgqACghi2f 1q7lXukyBjtYvG0mTFPv+po= =Mu6g -----END PGP SIGNATURE-----

[linux-audio-user] smurf - no sound

by Atte André Jensen

Hi I'm trying to get *any* input/output (MIDIin/audio out) going with smurf, but didn't succed so far. Is there any trick that one should know of? I don't need anything fancy, simply to be able to press a note on my Evolution keyboard and hear the sound comming from smurf as I edit. My soundcard is set up with ALSA + OSS emulation and works with other apps. I do realize that smurf is so old it's dead. What are other, more recent applications for editing soundfonts? I'm on debian/unstable... Thanks in advance for any advice. -- peace, love & harmony Atte

Re: [linux-audio-user] digital i/o

by Gerrit Niestijl

Hi, I have a card using the cmi8738 with digital IO, sold in the Netherlands under the name Trust (digital sound surroud 5.1). I payd euro 50,-- for it. This card is being sold under different names in different countries. It works OK with alsa and jack. > the cmi8738 chipset in the dio2448 works well (i have several). > The midiman seems a bit overpriced (~e120) as there are complete motherboards > containing this chipset for less than the price of the midiman:-) > Having said that, i havnt personally found a cheaper card. If you > find something, pls let us know:-) -- Gerrit

[linux-audio-user] New To List

by Chris Share

Hi, After reading an article about Linux and music in Sound On Sound recently, I thought I'd take the plunge and begin moving my music studio to Linux. Currently I'm using an Athlon XP-based PC and a PowerMac 7600/200. The PC contains a Hoontech DSP24 Value card and an MPU-401 style MIDI interface that I put together myself. The Mac contains a Yamaha SW1000 card and an Opcode MIDI interface. My main music software is Cubase, although I've used tons of other music software over the years. The main programs I'm interested using are Rosegarden and Ardour, although I'm also interested in looking at some of the softsynth stuff too. I work as a technical writer and have written some music software for Mac and PC (CS1 Background Edit) so I'm fairly computer literate. However, I have no experience with Linux. Initially, I installed Debian on my PC, however it didn't get along with my TFT monitor. I've since bought Red Hat 9.0. Which I'm just about to install. Hopefully it will be a bit easier to use! Before I begin the installation I was wondering if someone could fill me in on the current state of ALSA. I've had a quick look at some of the How-Tos however I'm not clear on how up-to-date they are. I'm currently looking at getting a new soundcard--the Hoontech was really only a temporary measure to get sound out of the PC. Unfortunately, it seems that the SW1000 won't ever be supported so it's not much use. I'd like a card with balanced 24-bit analog I/O and SPDIF I/O. The MiaMIDI card seems to have these features. Does anyone have experience with this card on a Linux system? I also thought that a Delta66 would be suitable too. Cheers, Chris Share

[linux-audio-user] Red Hat 9.0 is installed!

by Chris Share

Hi, After my recent "newbie" post I thought I'd let everyone know that I've successfully installed Red Hat 9.0. It correctly detected my video card and monitor, something that Debian couldn't do. The install process was very simple and well documented. Cheers, Chris
