ten years since 1.1.4r1!

Hello all,

as of today, it's exactly ten years since the first release of Ecasound 
under GPL!

I had been dabbling with the codebase already since 1997. But for the 
first few years, I was just using the software myself, i.e. just 
scratching my own itch. The thought of releasing the app for others to 
use, occured to me only in 1999. The first public mention of the app was 
on linux-sound mailing list:

  http://marc.info/?l=linux-sound&m=92851317730044&w=4

I immediately got a few response mails from interested people (Dan Boger, 
someone with a mail alias '17.hzV.tRL.478', Michael Stutz and Jeremy 
Hall), asking where to get a tarball.

This further encouraged me to license the app under GPL, and put a release 
out, which I did a few weeks later. Unfortunately, as often happens, the 
very first r1 release (out on 30th June 1999), had some rather severe 
bugs, so 1.1.5r2 followed on the next day (July 1st). First announcement 
mail was sent about 1.1.5r2 to linux-sound list:

  http://marc.info/?l=linux-sound&m=93079086212704&w=4

The rest of the history is already well documented in the archives of this 
list, and most importantly, in the git (formerly CVS) commit history.

I was aiming to release 2.7.0 today to mark the anniversary, but I simply 
ran out of time, and thus decided to just write this mail instead.

The best compliment I can offer is the fact that I can write an ecasound 
based project for around 5 years now. I don't think I could have been 
able to do this unless ecasound was so versatile, stable and 
full-featured. I can't recall anything that I haven't been able to do 
with it.

I'm more of a musician than a technician, and I'm not a C programmer. 
But there's so many hidden gems in ecasound's many features that I think 
anyone with an imagination could spend a lifetime writing ecasound based 
programs, front-ends and the like.

Thanks for the great programs and all the work you've put into it.

Rocco

AUTHORS-file (was: Re: ten years since 1.1.4r1!)

Hi all,

On Wed, 1 Jul 2009, Kai Vehmanen wrote:

thanks to a private mail I got after the ten year post, I now realized 
that the AUTHORS file is not quite up-to-date. Starting from the 2.2.1 
release, I've been tracking contributors in the release notes (as the 
release notes get much more publicity than the AUTHORS file -> posted to 
linux-audio-annonce list and usually end up in lwn.net weekly news). I 
kicked this off with:

  "Vanity Appeal :)"
  http://eca.cx/ecasound-list/2003/01/0048.html

The smiley is still in order, as I do think giving credits properly is a 
critical thing for any open-source project. We all benefit from 
contributions (not just patches, but all kind of help that pushes the 
project forward), so the least we can do is to list the people who have 
helped.

So I've now collected list of all contributors (altogether 90 people!) 
from the release notes (since 2.2.1) and added them to the AUTHORS file. 
This way the full list of people gets also distributed along with the 
release tarballs (the original release notes are not included).

So here's a verbatim copy of the added segment (also online at 
http://eca.cx/ecasound/authors.php and committed to the git repo):

Re: problem with path on 2.6.0 and latest dev snapshot

oh boy, this was one stupid bug. Thanks for your perseverance with this 
problem! I now figured this bug was introduce to 2.5.2 with following 
commit:

--cut--
commit 8917a0f6602bd6098dffe434f008458cb1199549
Author: Kai Vehmanen <kvehmanen -at- eca -dot- cx>
Date:   Fri Jul 11 01:22:46 2008 +0300

     Added new '-E' ecasound frontend option.
--cut--

... unfortunately I had not booted up my brain properly when committing 
that (or it had been in continuous use for too long ;)) and as the result, 
the change to frontend parser is simply braindead ('-E' is a frontend 
option and not handled by the libecasound parser). As a result, any 
argument containing "-E" substring was not correctly passed to 
libecasound. :( D'oh!

This also explains the earlier problems you have reported in April:

  "problem with long command line parsing?"
  http://www.eca.cx/ecasound-list/2009/04/0038.html

... e.g. in this case, "-o 
/Users/jayson/tmp/pymgen_tmp/GZC24e/audio-Et9gws.aac" had the infamous 
substring and was not correctly passed forward.

Sorry about the hassle! Bugs of this magnitude really should not slip 
through to releases.

Fix was just committed to the git repo, and here's also a snapshot:

Aha!  Well I am glad I could help in some little way.  I love ecasound :)

Thanks a ton for your hard work.

Songanalysis and LADSPA plugins

Hello all!
   I've known this package "songanalysis" for quite some time. But now I 
wondered, if it might be possible to build a LADSPA plugin from this, or if it 
would be possible to include it in ecasound as an option. It can do tempo 
analysis, but more importantly it can do frequency dependent volume analysis, 
which might be very helpful for text-based mastering. It uses a special scale 
Mel? or was it Cepstra? to set the static bandwidth. Not as good as graphic 
JaMIN output, but certainly of more help than ears only for a first stab. 
   The package is here:
http://nixbit.com/cat/multimedia/audio/songanalysis/
   You'll find a small description and a download link there.
   I know there's one limitation to the code as-is: It only works with 44100Hz, 
as I remember.
   I'd be greatful for any ideas, oppinios on this.
   Kindest regards
          Julien
