MY COMPRESSOR DOES NOT WORK!!

[gonzdi]

Hi Chameleon´s people,

I have a problem with the application that I am developing for the chameleon:

It consists of an audio compressor that I have already developed and works correctly, but the problem is in that it does not recognize me the tasks included in the "main.c" ('create_dsp_task' and 'create_panel_task').

I would like, if someone can, were checking the code to seeing if someone find the problem because i am a new developer and i do not find that. I will attach it in a file.

thank you very much for your attention and i hope your help !!

saludations from Spain!!

Hi Gonzdi!

to electro-music.com!

I had a look at the sources, and the first thing that hits me is that some of the files have strange extensions, like 'panelH.txt' and 'panelC.txt' etc.. Very strange - they need to be renamed 'panel.c' panel.h' etc.. That will stop the errors given for 'create_dsp_task' and 'create panel_task'. Also, the 'dsp' directory contains C sources of the same names as those in it's parent directory.

I cleaned up a little and tried a build, got some errors, fixed 'panel.c', line 243 by adding a quote to close the string - but there are more errors to be dealt with. I think you should have a look at the file structure of the example projects. Perhaps starting a new project and importing the files you need.

hi DrJustice,

thank you very much for your help!!

My intention is to develope an Audio Master with three filter-bands, a compressor, an expander and a signal limiter in each band, After that to include a master limiter and gain.

If to someone he/she is interested in this application and wants to help me with someone of the blocks, I will be grateful for it to him/her eternally!!

i will try to remake the project with the tutorial examples and then I will keep you informed!!

I have changed error files and now does not exist files incompatibility.

my problem now is that exist this error:

"makefile:17: *** commands commence before first target. stop
make[1]: *** [dsp/dsp_code.h] Error 2
make: *** [common] Error 2"

I attach the new file for if someone can solve it.

Thank you for your attention and apolologize by my insistence!!

Hi people!!!

after some months developing other algorithms and learning more about Chamie , i´ve returned to try this compress, and my new (but not the last... ) question is:

when i try to compilate all the program, doesn´t exist "errors", but it doesn´t let me to compilate it showing this text:

Unresolved Externals:
CRB_TEO (C:\.......\main.cli)
GRT (C:\...\main.cli)
make[3]: *** [/Chameleon.sdk/...../main.cld] Error 4
make[2]: *** [dsp/dsp_code.h] Error 2
make[1]: *** [debug] Error 2
make: *** [common] Error 2

Results : 1 Error(s), 0 Warnings(s)

Why could be it caused???

Another time, thank you for your attention and have a nice day

[DrJustice]

Since the compiler complains about 'Unresolved Externals:' CRB_TEO and GRT, I'd search for those in the sources. If you can't catch them, we'd need to se the code to help any further.

ok Mr. Justice, I have tried to resolve this error for five days, and can´t see the solution. I think that the target to resolve it is in the "main.asm" where i have forgotten any step or any port activation that i can´t see. I´ll attach the code and if you could help me, when you build it only will have this anounced error (and hope that will be the last...).

another time, a lot of thanks for your attencion!!!!

OK, I've tried to build the project now.

The symbol 'CRB_TEO' as referenced in 'main.dsp' line 254 and 289, should be 'CRB_TE0', i.e. use the digit zero, not the letter O ('CRB_TE0' is defined in 'SDK\include\dsp\dsp_equ.asm').

The missing 'GTR' symbol is not defined anywhere. However, there's a 'GRT' symbol defined in 'main.dsp' line 35. I changed that definition to 'GRT' and it then gets past that error.

Of course, now that the build gets a bit further there are other errors (in 'panel.c' and 'panel.h'). This is to be expected since the build didn't get that far previously. So there's a little bit more work for you in cleaning up the panel code

Hi,

finally it´s done, the audio compress runs ok. It´s not so complete like others, but make the basically function: "simple but easy".

I attach the code, the interface compilation and a litlle resume for everybody.

Thanks to everybody for your help and patience

Now....for the audio limiter!!!

user´s manual:
this audio compress consists of a separating filter of three bands where each band is modified separately with: RATIO, THESHOLD and INPUTLEVEL.

Then, when you conect the chameleon, you will see the "Output Gain" which is posible to modified with control1.

If you press edit buttom, access to Proccess window where you can change the band to compress with "part" parameter (LPF,BPF,HPF).

If you want to change the function, with "param" you will choose between ratio, threshold and Input Level.

Finally, if you change the "value" button, you will be modifying each of the previous parameters
