A short story: from zero to recording the drums in a budget

by Carlo Ascani

Hi guys, I own an acoustic drum, and I wanted to record it. My set looks like this [1], and I wanted 8 mics to record it. So, starting from *just* the drums, I bought everything I needed: 1. The Mixer I got a second hand Soundtracs Topaz Micro (I used its Inserts as Direct Outs) for 220 euros 2. The PC I got an IBM Thinkcentre 8215 for 50 euros 3. The converters I got an Echo Layla 20 for 50 euros, it has 8 analog ins and it is really well supported by alsa. 4. The Monitors I got a pair of second hand KRK Rockit 5 for 150 euros 5. Cables and mic stands Got them for around 250 euros 6. The mics I got an Audix D6 and a Sennheiser e609 for kick, a Revox m3500 and a Beyer m610 for the snare, two Sennheiser e609 for the floor toms and a pair of Sennheiser e614 as overheads. The total cost of those mics (second hand) is 600 euros. So, the total price of the whole thing was around 1320 euros! Here are some audio clip of the result, dry recording [2] and processed with some eq, compressor and reverb [3] So guys, what do you think? If I would improve the quality of my recordings, where should I spend more money?

Suppress the GUI of calfjackhost?

by Jonathan E. Brickman

I'd love to be able to run one of my standard calfjackhost chains, with a command-line switch to suppress GUI. Is there a way? -- Jonathan E. Brickman Ponderworthy Music | jeb(a)ponderworthy.com | (785)233-9977 | http://ponderworthy.com

[ANN] Vee One Suite 0.5.1 - One second official beta release!

by Rui Nuno Capela

Howdy, The gang-of-three aka. the Vee One Suite of old-school soft(ware)-instruments, featuring synthv1 [1], a polyphonic synthesizer, samplv1 [2], a polyphonic sampler and drumkv1 [3], as a drum-kit sampler, are once again released in beta phase though. The changes for this one second beta release are the following: - Fixed LV2 plugin relative/absolute file path state resolution. (drumkv1 [3] only). - One decimal digit added to all scalar parameters and knobs. - Stand-alone JACK client ports outrageously renamed from a zero based numbering scheme into a plus one natural one. - Experimental LV2 Time/position atom-event support (Delay BPM). Please, don't hesitate to ask whether any of the above esoteric babbles doesn't get you on to update as soon as you can. One special note goes for all the users out there of drumkv1 [3] LV2 genre: the update is not just interesting but a must, seriously ;). As usual, all is available in dual form: - a pure stand-alone JACK [4] client with JACK-session, NSM [5] (Non Session management) and both JACK MIDI and ALSA [6] MIDI input support; - a LV2 [7] instrument plug-in. The Vee One Suite are free and open-source Linux Audio software, distributed under the terms of the GNU General Public License (GPL) [8] version 2 or later. The gore details are as follows ;) * synthv1 - an old-school polyphonic synthesizer [1] * synthv1 0.5.1 (second official beta) is out! synthv1 is an old-school all-digital 4-oscillator subtractive polyphonic synthesizer with stereo fx.

A Gentle Introduction to SuperCollider

by Bruno Ruviaro

Hi all, I would like to share with everyone this new SuperCollider tutorial I wrote over the Summer. It's specifically written for total beginners, and it's Creative Commons licensed, so feel free to share, copy, distribute, remix...: PDF: https://ccrma.stanford.edu/~ruviaro/temp/00_PDF_A_Gentle_Introduction_To_Su… Source files (LaTeX): https://github.com/brunoruviaro/A_Gentle_Introduction_To_SuperCollider ... and in case you'd like a nicely printed copy at cost value: http://www.lulu.com/shop/bruno-ruviaro/a-gentle-introduction-to-supercollid… The title is a little homage to Touretzky's Common Lisp book, which I loved when I read it years ago. This tutorial is also very much indebted to David Cottle's intro chapter on the SuperCollider book. I consider this tutorial to be in "beta version" -- I'll try it for the first time in a classroom situation this Fall, and probably will change things over time. So I very much welcome feedback from anyone who cares to read it! Best, Bruno

html5 audio through jack

by Iain Mott

Hi list, I'm thinking of updating some of my web pages to use multi-platform flash/html5 audio players, at present they use flash only and won't play on iPads for example. Due to some problems I was having with pulse audio in relation to my HDSP interface I have recently disabled it and all my audio is running via jack/alsa and the HDSP interface. With flash in firefox, there are no problems and the audio plays. My .asoundrc is configured with the following: pcm.rawjack { type jack playback_ports { 0 system:playback_1 1 system:playback_2 } capture_ports { 0 system:capture_1 1 system:capture_2 } } pcm.jack { type plug slave { pcm "rawjack" } hint { description "JACK Audio Connection Kit" } } pcm.!default { type plug slave { pcm "rawjack" } } HTML5 players in firefox don't play however via jack. When pulse was enabled, HTML5 content would play through the computer's built-in sound card. Now that it's disabled I can't get it to play through jack. An example page with a HTML5 player is here: http://www.html5tutorial.info/html5-audio.php Any suggestions please? A modification of the .asoundrc? I'm running Ubuntu 14.04 Thanks,

control surfaces

by Kelly Hirai

hey linux audio users, about a year ago i purchased the korg nanokontrol one when they were dumping them to make room for the nanokontrol II. the last month i'm finally getting to using it for some csound live processing. but im beginning to find shortcomings. for one i could use more knobs. also 14bits of resolution would be nice. finally it would be nice if when i reassign the knobs it would be nice to be able start from the values they are operating on. so im looking into the bcr-2000-b by behringer. any linux users had any experience with this device? any other device suggestions for a budget minded music coder? k.

Low-latency Bluetooth 96kHz audio?

by Jonathan E Brickman

Anyone know if this: http://goldkabel.de/index.php/bluetooth-audio-receiver.html works well with Jackd? Can it run <5ms latency at 96 kHz with a good Bluetooth 3.0 adapter? Jonathan E.

How far we've come!

by Russell Hanaghan

One of the other posts got me thinking a bit, re: all things linux audio. There are some folks here that kicked over the very first stones. The practicalities and useful application of current day (perhaps taken somewhat for granted) apps (Jack, Ardour , LADSPA... Muse and Rosegarden ... PD, timidity... Et al, were there in some form when I started in 2000, digging in the fields of realtime kernels and lower latencies (kernels 2.4 - 2.6 I think).. Trying to put old laptops and boxes that couldn't run XP to useful tasks...etc. I don't necessarily have a point to make other than to perhaps see some of where we've been, to further appreciate where Linux Audio is today! Um, we thought man would be on Mars and further when I was a boy. :) we may could have been! Money required to sustain such development is relevant! Developers o any kind can hardly afford no pay... They too have bills to pay, educations, sustenance and roof over thine heads! Many have come and gone! Some figured how to walk the crevasse of 'free' vs respective remuneration and their development efforts are rewarded with supplemental funds. I don't think any serious linux audio folk have gotten rich from Linux Audio have they? I would simply like to acknowledge the general core of devs. Without you, we'd all having nothing linux audio to bitch about!! :) I don't care to mention names. They know who they are. I met a few along the way. At San Francisco City Hall of all places!! 1 of which I still see here, 1 I do not. I personally rely heavily upon Linux and Linux audio these days. It's cost me extreme little in $$ stacked next to proprietary OS. It's powered several semi pro studio platforms, been used at various gigs over the years to record, perform, etc. A toast! :) to those who persist! Cheers! ~ Russell

fabla GUI doesn't render

by Paul Coccoli

I just cloned the ntk and fable git repos (well, within the last day or two), installed all the other dependencies, and build fabla. When I run it with jalv.gtk, a window appears but the GUI is not rendered. There's nothing unusual in the output in the shell I ran it from. Starting jalv.gtk with the -d option results in a segfault. This is on fedora 19. jalv-1.4.0-2.fc19.x86_64 cairo-1.12.14-2.fc19.x86_64 cairomm-1.10.0-6.fc19.x86_64 libsndfile-1.0.25-7.fc19.x86_64 lv2-1.6.0-2.fc19.x86_64 Has anyone seen this issue before?

Hydrogen - multi banks per instrument

by Aurélien Leblond

Hello, I'm currently working on a feature for Hydrogen to have multi banks per instrument. In a nutshell, if you have drum samples with direct and overhead recordings, you can put those together under the instruments - one instrument Snare for example with the band direct and the bank overhead). In the Hydrogen mixer, you can chose how much direct or overhead is needed, changing completely the tone of the drums. You can chose how many banks you have per instrument, and the gain of each bank in a given instrument. A very (very very.......veryveryvery) early version is available here: https://github.com/blablack/hydrogen Very early version as the main feature works, but for example I highly doubt saving/loading songs would work just yet and the mixer GUI goes a bit crazy when banks are added/removed, I'm in the process of a massive testing/bug hunt... I would be very interested to get some early feedback, both on the feature and (for the most courageous) on the code itself. Thanks in advance ladies and gentlemen! Aurélien
