[LAU] M-Audio Fast Track Pro: unreliable, distorted recording

by Lewis Pike

I'm the (un?)lucky owner of an M-Audio Fast Track Pro USB audio interface and I'm having some serious problems getting this device to record audio reliably under Linux. I've been using arecord and occasionally Audacity for all of my testing. My problem is this: Recording a take works about 80% of the time. In the remaining ~20% of cases, the captured audio is extremely loud with severe digital distortion. Once this problem shows up, it persists for any subsequent takes. The only way I've found to make the problem go away, at least temporarily, is to power-cycle the Fast Track Pro. I considered the possibility that this particular device might be defective, but it seems to work wonderfully under Windows. I'm calling out to other Fast Track Pro users in the hope that someone out there has encountered the same problem and better still, found a solution. Any suggestions at all would be greatly appreciated! .lewis

[LAU] Zoom U-25 Audio Interface

by Max

Nowhere on this page it says that this device is class compliant, but it claims that there is no driver necessary for OS X and iOS which seems a good indicator for it. What do you you think of this interface? https://www.zoom.co.jp/products/production-recording/audio-interfaces/u-24-… 89 € there is also a version with digital interfaces: https://www.zoom.co.jp/products/production-recording/audio-interfaces/u-44-… 149 €

[LAU] Microphone advice

by david

Good evening! I currently don't have a microphone of any sort. I don't generally do a lot of audio recording, but I do sing (sort of), play a Garcia Concert Model 3 nylon string classical guitar, and occasionally do silly things like play my collection of wind chimes ... So - what would be a good, reasonably-priced mic for those uses? Thanks. -- David W. Jones gnome(a)hawaii.rr.com authenticity, honesty, community http://dancingtreefrog.com

[LAU] Help getting sound from Cakewalk UA-25 EX to Ardour

by Hernán Labbé Grünberg

Hi everyone, This is my first email to this list. Apologies in advance if I break any conventions I am unaware of. I am a long-time musician, but just getting acquainted with audio in linux. I have a very simple goal of getting sound from a plugged instrument to my computer via a usb-interface, the Cakewalk UA25-EX, which I know works with linux. So far the instrument's output is received by the interface, and the interface is recognized by the computer. I asked in the ardour forums on how to get ardour to recognize that the input for audio is the usb interface. They suggested <https://community.ardour.org/node/15577> I use ALSA instead of jack to connect to Ardour. The interface of Ardour allows me to select the Cakewalk interface as input and output, but when I play the instrument I see that while the interface gets the signal, the audio is not received by Ardour. If I change the input to my laptop's microphone, then I do get a signal. The problem, then, lies in the connection between the interface and Ardour (or the computer?) I checked the Alsamixer levels and they are not at 0. The advice from the Ardour forum was to contact this mailing list, as I probably need some help checking the connection of the usb interface to the computer. Thanks in advance

[LAU] The Bay of Atlantis

by Louigi Verona

Announcing a new release of project "droning", tune 281 "The Bay of Atlantis". *Stream it here:* https://louigi.bandcamp.com/album/281-the-bay-of-atlantis *Word from the author:* Extensive work went into this creation. I wanted the tune to create a feeling that this is one solid composition, not a soundtrack with distinct segments, but something rather like an ocean which is in one instance is calm and in the other - furious. But still just one single ocean. To all of you travelers out there, and to those of us who find visiting nonexistent places important. *Technical specs:* Qtractor, Rakarrack, Carla, Kluppe, seq24 and a number of LV2 plugins. Zyn is used, although a number of sounds came from other sources. -- Louigi Verona https://www.patreon.com/droning https://louigiverona.com/

[LAU] has anyone used i.MX6 device with ALSA SoC driver?

by Chris Caudle

Has anyone on the list used a device with a Freescale/NXP i.MX6 processor and used the ALSA drivers for the on-chip audio? I am interested in a device with that processor, but I don't want to purchase one without some verification that audio is usable. -- Chris Caudle
