Hi,

I always thought that the default value for 0dbfs was, as stated here
(http://csound.com/docs/manual/Zerodbfs.html) and elsewhere, equal to
32767. However, "print 0dbfs" returns 32768. What's going on with that?

Cheers.

It’s 32768, the manual needs to be fixed.

Oh, that's interesting. So instead of, say for example the −32768 to
+32767 range found on a 16-bit PCM encoding, in Csound a sine oscillator
would actually go from −32768 to +32768!

No, I think the range is still the same, but the Odbfs value is the abs max of it.

Indeed, since within Csound everything is in floats, it would.  Of 
course, as soon as you convert to any integer format, you will hit a 
problem. Which is one of the reasons why it is never recommended to take 
or normalise a signal right up to digital peak.

I guess Windows?  Not my area but it looks like nissing rt libraries or

Thank you.  But tt audio is working using Csound from the command line, so it suggests the rt libraries are present working.

Thank you.  Tried setting OPCODE6DIR64 from CsoundQT, and also by using the setOptions library call, but no luck with either.

This is a custom application? You can try calling csoundSetGlobalEvn() to set OPCODE6DIR64
http://csound.com/docs/api/group___m_i_s_c_e_l_l_a_n_e_o_u_s.html#ga0183dad9bbc4961d66a280e5292091ed

But to be honest, I have rarely ever had to do this. What compiler are you using?

This looks to do with not finding the opcode directory. If it happened to you, you would not have
any other plugins. Did we use VS in 6.09? I think we only had mingw/msys binaries. Maybe that
is a difference.

Thanks very much for the suggestions.

I am using the library in the binary downloaded from the Csound website (which I had done for 6.09), so I am guessing that the environment under which they were compiled should not matter. Note, reinstalling 6.10 didn't help.

I was using -+rtaudio=pa_bl under 6.09 (which is what CsoundQt is using), then when that failed under 6.10, also tried doing without the -+rtaudio option, but that results in the
"unknown rtaudio module: 'PortAudio', using dummy module" instead of the unknown rtaudio module: 'pa_bl', using dummy module" message.

Guessing that the missing plugin is rtpa.dll, I tried loading it as a library, and that works--I note that it relies on portaudio_x64.dll.

Putting both csound6_x64/bin and csound6_x64/plugins64 in the PATH doesn't seem to help either.

I am now looking at csound source code to try to see if I can find a clue.

Thanks again.

Can you run a simple real-time audio instrument from the command line with csound.exe? Or do you get the same error there? I

This looks to do with not finding the opcode directory. If it happened to you, you would not have
any other plugins. Did we use VS in 6.09? I think we only had mingw/msys binaries. Maybe that

Hi,

I have been using the Csound library (csound64.dll) from a custom C++ program
under Windows, but since I have switched from 6.09 to 6.10, my program no
longer outputs audio (it works if I switch modes to save the output as a
file).  Specifically, Csound prints the message:

     "unknown rtaudio module: 'pa_bl', using dummy module"

and if I remove that option to fall back on the default:

     "unknown rtaudio module: 'PortAudio', using dummy module"

Csound 6.10 works fine from the command line. OPCODE6DIR64 points to
(...)\Csound6_x64\plugins64\ and is set as an environment variable for all
users, and PATH (for all users) includes (...)\Csound_x64\bin. The version
details are:

This looks to do with not finding the opcode directory. If it happened to you, you would not have
any other plugins. Did we use VS in 6.09? I think we only had mingw/msys binaries. Maybe that
is a difference.

This is a custom application? You can try calling csoundSetGlobalEvn() to set OPCODE6DIR64

Hi,

I have been using the Csound library (csound64.dll) from a custom C++ program
under Windows, but since I have switched from 6.09 to 6.10, my program no
longer outputs audio (it works if I switch modes to save the output as a
file).  Specifically, Csound prints the message:

    "unknown rtaudio module: 'pa_bl', using dummy module"

and if I remove that option to fall back on the default:

    "unknown rtaudio module: 'PortAudio', using dummy module"

Csound 6.10 works fine from the command line. OPCODE6DIR64 points to
(...)\Csound6_x64\plugins64\ and is set as an environment variable for all

Using -+rtaudio=winmm results in the csound message:

"rtaudio: WinMM module enabled"

So it looks like that plugin is working.

I don’t think there are issues to be found in the sources. Do you know if any other plugin is found?

Thanks very much for the suggestions.

I am using the library in the binary downloaded from the Csound website (which I had done for 6.09), so I am guessing that the environment under which they were compiled should not matter. Note, reinstalling 6.10 didn't help.

I was using -+rtaudio=pa_bl under 6.09 (which is what CsoundQt is using), then when that failed under 6.10, also tried doing without the -+rtaudio option, but that results in the
"unknown rtaudio module: 'PortAudio', using dummy module" instead of the unknown rtaudio module: 'pa_bl', using dummy module" message.

Guessing that the missing plugin is rtpa.dll, I tried loading it as a library, and that works--I note that it relies on portaudio_x64.dll.

Putting both csound6_x64/bin and csound6_x64/plugins64 in the PATH doesn't seem to help either.

I am now looking at csound source code to try to see if I can find a clue.

Thanks again.

This looks to do with not finding the opcode directory. If it happened to you, you would not have
any other plugins. Did we use VS in 6.09? I think we only had mingw/msys binaries. Maybe that
is a difference.

that’s good. Now maybe there is a reason why rtpa.dll is not loading. Make sure there are no older copies of that dll around

Oh dear, this is embarrassing.  Rebooting seems to have fixed it. Evidently, PortAudio can get wedged somehow.

Thanks again for all the helpful responses and very sorry to waste people's time.

I was going to suggest just that! Try profiling with Dependency Walker

and enable Full Paths to see the path that it's being used.

I just build a simple app here on Windows using VS, and it found the

realtime audio module without any hiccups. I'm not sure what's going wrong

with your application. Do you have Pure Data installed, or any other audio

software that uses portaudio? If their directories are on the system paths

it could lead to issues. Does the depwalker(http://www.dependencywalker.com/)

application list the locations of the libs that are being loaded? If so,

that might be something to try.

and no extra copies of portaudio_x64.dll either anywhere in the system?

that’s good. Now maybe there is a reason why rtpa.dll is not loading.

Make sure there are no older copies of that dll around

Using -+rtaudio=winmm results in the csound message:

"rtaudio: WinMM module enabled"

So it looks like that plugin is working.

I don’t think there are issues to be found in the sources. Do you

know if any other plugin is found?

Thanks very much for the suggestions.

I am using the library in the binary downloaded from the Csound

website (which I had done for 6.09), so I am guessing that the environment

under which they were compiled should not matter. Note, reinstalling 6.10

didn't help.

I was using -+rtaudio=pa_bl under 6.09 (which is what CsoundQt is

using), then when that failed under 6.10, also tried doing without the

-+rtaudio option, but that results in the

"unknown rtaudio module: 'PortAudio', using dummy module" instead

of the unknown rtaudio module: 'pa_bl', using dummy module" message.

Guessing that the missing plugin is rtpa.dll, I tried loading it

as a library, and that works--I note that it relies on portaudio_x64.dll.

Putting both csound6_x64/bin and csound6_x64/plugins64 in the PATH

doesn't seem to help either.

I am now looking at csound source code to try to see if I can find

a clue.

Thanks again.

This looks to do with not finding the opcode directory. If it

happened to you, you would not have

any other plugins. Did we use VS in 6.09? I think we only had

mingw/msys binaries. Maybe that

is a difference.

Have you tried setting the device with the  -+rtaudio flag? I

didn't notice any problems when I started building with 6.10, but I don't

use Csound to output audio, so I guess i wouldn't see that error.

Thank you--I overlooked that one. Added the call to

csoundSetGlobalEvn, but still no luck.  The compiler is Visual Studio 2017,

via QtCreator. No change in compiler or IDE since I switched from 6.09

(with rt audio working) to 6.10.

This is a custom application? You can try calling

csoundSetGlobalEvn() to set OPCODE6DIR64

But to be honest, I have rarely ever had to do this. What

compiler are you using?

Thank you.  But tt audio is working using Csound from the

command line, so it suggests the rt libraries are present working.

I guess Windows?  Not my area but it looks like nissing rt

libraries or broken ones.

Hi,

I have been using the Csound library (csound64.dll) from a

custom C++ program

under Windows, but since I have switched from 6.09 to 6.10,

my program no

longer outputs audio (it works if I switch modes to save the

output as a

file).  Specifically, Csound prints the message:

    "unknown rtaudio module: 'pa_bl', using dummy module"

and if I remove that option to fall back on the default:

    "unknown rtaudio module: 'PortAudio', using dummy module"

Csound 6.10 works fine from the command line. OPCODE6DIR64

points to

(...)\Csound6_x64\plugins64\ and is set as an environment

variable for all

users, and PATH (for all users) includes

(...)\Csound_x64\bin. The version

details are:

    Csound version 6.10 (double samples) Jan 31 2018

    [commit: f5bcd83a9799536980d0f674bb7525f45f800490]

    libsndfile-1.0.29pre1

Thank you for any suggestions. Apologies if this is a "duh"

question.
