[Sugar-devel] Record Activity (audio)

[Art Hunkins]

Tom -

So much for Record and the EeePC900 ;)

I gather that was expected from the previous reports.

Again, is anyone actively working on Record audio to get it to be more reliable?

  ART;

  I just tested Strawberry(Soas-v1) and Blueberry(Soas-v2) on EeePC900

  Strawberry: record 64=yes (no sound)
           65,67,79=no

  Blueberry:    record (66,67,79)=yes (no sound)
           60,61,62,64=no 

  I downloaded all of the record .xo to a USB stick 

  http://download.sugarlabs.org/activities/4081

  And then drag-dropped them into the sugar -journal of the test USB Soas Stick 

  (I had to erase ;-right click;-previous Record-xx.xo I had tested from the sugar journal prior to next test)

I'd guess the audio issues have to do with the hardware as well - though I 
did not test on any of the "problem" systems enumerated in your link.

All my SoaS tests were on the same desktop computer - i.e., same hardware. 
As noted, some versions of Record worked flawlessly (SoaS), others with 
glitches (major or minor) and/or artifacts, and some not at all (either no 
save, no play, even no load - as in Record v64 with Blueberry, "failed to 
load plugin").

These results would seem to indicate issues *in addition* to hardware 
variations.

    I've recently developed a 4-file mono/stereo realtime mixer/processor 
application in Csound, and it works well on the XO's and versions of 
SoaS. So I was thinking of porting it in Python to Sugar as an Activity.

One problem: currently Csound imports standard uncompressed soundfiles, 
and doesn't work with ogg. The Record Activity only outputs ogg, it 
seems. I would not consider porting my application to Sugar if Csound 
could handle a filetype that Record can output.

Question #1: what are the chances that Record can be enhanced to produce 
wav files?

Question #2: what are the chances that Record can be made to work 
dependably on Sugar .82-.88 (at least)?

With regard to question #2, I get very spotty (mixed) results for Record 
(audio), as follows:

XO-1.0: Record 59 works fine; higher versions (including 64) have major 
audio dropouts.
XO-1.5: Record 64 bad, with major dropouts; v67 is semi-OK as is v85 
(recording artifacts and occasional glitches)
Strawberry: Record 64 works fine; further upgrades don't (including v66, 
v79, v85) - *nothing (including won't save or play)*
Blueberry: v66 is semi-OK (slight artifacts, no dropouts); v64, v79 and 
v81 - *nothing*
Mirabelle: v64 not tested; otherwise same results as Blueberry


      look at: 
http://wiki.sugarlabs.org/go/Features/Soas_V4/ASLOxo_Activity_Test_Table#Activity_Test_Results

"...+camera NO sound Asus Aspire One, NO camera +sound EeePC900''

It depends on the Hardware it seems..

I will try some more testing..

    Bottom line: not encouraging. Is anyone currently working on Record?
