Flight case
|
2023-01-23 |
|
|
Pas beaucoup de nouveautés dernièrement !
Je viens de concevoir et defabriquer un flight
case pour Pédale Vite.
Détails ici.
Pendant ce temps je m’éternise sur une modification du logiciel interne qui me
pemettra de placer facilement des simulateurs d’ampli en sortie sans interférer
avec les programmes d’effets.
À suivre…

C++ file templates
|
2022-06-02 |
|
|
I ported my file template generator for C++ source to a
VSIX extension for VS2019, written
in C#.
It was previously a set of Visual Basic macros but worked only with
VS2005.

ChickenDream
|
2022-04-11 |
|
|
ChickenDream is a new plug-in for Vapoursynth and Avisynth+.
It emulates film grain using a realistic model, described in the following papers: here and here.
It gives stunning results, especially with coarse grain, where usual grain generation algorithms fail hard.
However the results have to be balanced with the highly CPU-intensive processing.
I also updated fmtconv, now using
Vapoursynth API v4.

Cass&Tord

Another music project: Cass&Tord.
We recorded an EP earlier in January in Trash Palace Studio, it is now
available on the band website.

Updates for fmtconv
|
2021-10-30 |
|
|
I spent the last few weeks updating fmtconv,
notably by adding a plug-in for Avisynth+ and
improving the HDR support.
|

Graoumf Tracker 2 r26
|
2021-07-27 |
|
|
Another Graoumf Tracker 2 update, this time
with a surprise contribution from long-time user David L.
So now there are at least two GT users across the world for this
25+ years-old piece of software.
Also fmtconv has been updated to r23.

|
Graoumf Tracker 2 r25
|
2021-03-14 |
|
|
Quick update for the very dusty Graoumf Tracker 2.
JB/dDash asked me a functionnality to load dozens of samples in a single click.
|
|
More updates
|
2020-10-10 |
|
|
There is a new release of the HIIR library
again (v1.32).
I also released updated versions of the
Dither (v1.28.0) filters set for
AviSynth as well as the MVTools (v2.6.1.0)
and AVSTP (v1.04).
|
|
HIIR library updated to v1.31
|
2020-07-15 |
|
|
The HIIR library now includes a function to
desgin a half-band filter with a requirement on the group delay.
This is useful to get integer group delay values (in samples) that can be
easily compensated when mixing processed and unprocessed signals.

Nouvel article : Introduction aux filtres numériques à topologie préservée
|
2020-04-23 |
|
|
J’ai pondu un petit article sur la
conception de filtres numériques modélisés à partir de circuits analogiques.
Le sujet est évidemment très vaste et l’article en égratigne à peine la
surface.
Toutefois il devrait donner suffisamment d’outils, de méthodes et de pistes
pour commencer à coder des filtres réalistes.
Je voulais surtout présenter des méthodes alternatives à la BLT classique,
tout en rendant compréhensible un sujet sur lequel il existe peu de
ressources simples destinées aux novices, allant droit au but.
C’est une sorte de marche intermédiaire entre le sol de ce bas monde et les
annexes techniques très formalisées des simulateurs de circuits comme Spice
ou Qucs.

HIIR library updated to v1.30
|
2020-03-13 |
|
|
For this Friday the 13rd, the HIIR library
got a major update.
It now supports double (64-bit float) operations.
There are SSE2 and AVX implementations, thanks to Dario Mambro.
I took the opportunity to add AVX-512 support, as well as missing
parallel N-channel implementations for the Hilbert phaser.
I improved a few things with the SSE and NEON single-channel resamplers, too.
I checked compatibility and performances with the most recent compilers
on Intel and ARM platforms.

Pédale Vite v2
|
2019-11-04 |
|
|
It’s been a while I was preparing this, and now I am proud to release
Pédale Vite
version 2.
It includes a custom audio board, with high impedance inputs and fully
balanced inputs and outputs, as well as a better latency.
It is also much thiner, which is more convenient to use and carry.
The display is bigger and of higher resolution, which means I could develop
a more graphical-oriented user interface.

Sound of the Void
|
2019-08-14 |
|
|
It’s time to introduce my rock/grunge/punk/psyche band,
Sound of the Void, with Alice
(vocals, bass) and Greg (drums, synth).
I’m playing the guitar.
The band was founded in 2016.
We currently have just a single track recorded (in our own studio) and
released, but others will follow soon.
We’re also doing gigs sometimes, in France at the moment.
Stay tuned!

HIIR library updated to v1.20
|
2019-06-23 |
|
|
After updating a few small things in HIIR while working on
Pédale Vite, I
realized that the published version was very old.
So I brought everything together and released a new version of the
library.
What’s new? Arm NEON support, 4-channel SIMD processing, better support for
modern compilers, C++11, etc. Enjoy!

Introduction video for Pédale Vite
|
2018-07-01 |
|
|
I did an introduction video to present
Pédale Vite.
It shows the main functionalities of this DIY pedalboard.
19 minutes, French dub with English subtitles.
The download link for the video is in the Pédale Vite homepage, but
Google worshippers can also find it on
Youtube.

SplitMix
|
2017-11-08 |
|
|
Another guitar pedal build: SplitMix.
It allows switching between two effect chains.
It offers two modules: a splitter sending the signal into two audio paths,
and a mixer combining their outputs to produce a single signal.
The mixer can blend both chains or select one of them with the help of
the footswitch.
The pedal fits into a 1590BB enclosure and requires 9V power (or more).

|
|
Building instructions for
Pédale Vite
have been translated to English.
Now only the user manual requires a translation.

Aélis, an FX pedal for the voice
|
2017-08-23 |
|
|
Aélis is an effect pedal to process
the voice.
It was primarily designed with reverb in mind, but can achieve several other effects.
Aélis is build around the Spin FV-1 DSP and contains a microphone preamplifier (but without phantom power).
Building instructions (in English et en français) and all required resources included.
Pédale Vite was also updated more or less regularly since the previous news.
|
|
We’re getting closer
|
2016-12-31 |
|
|
Almost complete building instructions and user manual for
Pédale Vite.
There is now a Github repository for all the documentation and source
code.
There are a new effects and a some UI changes in the pedalboard
itself.

Update
|
2016-07-30 |
|
|
A few additions for
Pédale Vite,
and a new Graoumf Tracker 2 version.

Pédale Vite
|
2016-04-10 |
|
|
(Sorry, French language ahead)
Je viens de me lancer dans un projet un peu fou et sérieusement
chronophage : la conception et la réalisation de
Pédale Vite,
un pédalier multi-effets pour guitare électrique (ou basse, ou n’importe
quoi d’autre qui fait du son).
Je n’en suis encore qu’au tout début, mais j’espère bien aboutir à
quelque chose d’utilisable.
La page sera mise à jour sporadiquement en fonction des avancées ou
des reculs.

fmtconv update
|
2016-03-08 |
|
|
fmtconv has been updated to r18 and now
includes chromatic adaptation (primaries and reference white).
Now this tool should be complete enough to accuratly convert video tracks
between almost any standard.
