Gsoc 2008

Hi,

I would like to apply for GSOC 2008 and I am interested in the
following two projects (quoted directly from the webpage)

Audio Ideas: ReSampling and Pitch Shifting

Questions:
(i) I am not sure where to post as a quick search did not reveal any
GSoC mails. I have already subscribed to the development list.

(ii) I have not used the SDL libraries but have have used it to
compile ffplay of ffmpeg.

(iii) I am familiar with video decoders (x264), Linux device drivers
(e1000 in particular), signal processing algorithms. I would like to
foray into audio algos and the project on audio resampling attracts me
at this stage.

(iv) Is there a IRC channel on Freenode that I can hover around?

Thanks for any help in advance,

PS: My exams just got over and the deadline got extended. Hence the
revival in interest to participate in GSoC.

Hello !

(iv) Is there a IRC channel on Freenode that I can hover around?

Yup it is #SDL on Freenode.

We can discuss GSoC projects on this mailing list.

There’s an #SDL, I think.

Looking forward to reading everyone’s GSoC applications,

You think? :)On Thu, Apr 03, 2008 at 01:14:43AM -0400, Ryan C. Gordon wrote:

Hello !

You think? :slight_smile:

:slight_smile:

It could be also #libSDL, no it is #SDL.

I only idle in IRC channels named after me. :slight_smile:

Hi there, sorry if an email appears twice but the last seems to be lost
awaiting moderator approval.

I’m interested in submitting an application for one or more of the audio
projects in the GSOC. Having just realised that GSOC has started and the
deadline is fast approaching, and being a SDL virgin, I was hoping to
ask a couple of questions:

Am I correct in saying, for example that alsa, arts, esd & pulseaudio do
not have implementations, whereas coreaudio and windows dx do is this
correct? What systems are considered priority if this project were to go
ahead?

The brief mentions ensuring that the API meets the needs of games - are
there any outstanding feature requests or improvements which the
community desires?

Thanks and regards,
Dougie–

Implementations of what? Recording? Nothing has that implemented yet.

All systems are “important,” of course, but if I had to pick three, it’d
be CoreAudio (Mac OS X), windib (Windows), and ALSA (Linux).

(hmm…is it time to move up the audio code up from DirectX 5 yet?)

–ryan.

You’re correct I meant recording implementations. Sorry, I assumed from the blurb that audio capture had been implemented on some systems and I only had time to very briefly scan the code.

With respect to sample rate conversion, is there any known reason not to use libsamplerate? It claims to be very easily portable.

Cheers,
Dougie-------------------------

Hello !

You can use libsamplerate only under GPL or a commercial license.
This would hurt SDLs LGPL.

Is this the same for the revised BSD license used in the Speex codec
also? http://www.speex.org/--

I’ve submitted 2 proposals, comments from mentors welcome, although I
appreciate that it is quite late in the day. :slight_smile:

Thanks for the interest! We received many proposals, and we’ll be going
through them in the coming days giving feedback and rating them.

See ya,
