Looks okay so far.
So the delay is due to the DSP implementation, since the StreamCopy DSP first reads the buffer from the original stream (ChannelHandle) and then writes them to the StreamCopy.
So to reduce the latency you might reduce the output buffer (BASS_ChannelSetConfig).

The delay is getting a bit better but not perfect. If the buffer is under 150 it´s getting bad and even the "normal" sound stagnates.

A better solution will come with BASS 2.4, since here BASS will support PUSH streams - and so the StreamCopy DSP will be changed to leverage this new feature.

So I´m gonna wait for BASS 2.4. Any idea when the release is??

However, I don't fully get what is not working (beside the delay)?
Meaning, if you use both PFLs for Player 1 and 2 - are you using two instances of the StreamCopy DSP?

My fault, it works with both channels... 

The BufferStream DSP works only with decoding streams (and there you don't have any speaker flags, thats why the StreamFlag property is only a getter there.

But yes, you could BASSmix to achieve the same (that's actually what I am doing).
Each mixer channel will then represent the 'physical' output stream.
And your players just deal with decoding channels, which are added to the respective mixer as sources.
In this case you then must use the BufferStream DSP (as this one deals with decoding channels) - and this one will then also have no latency effect (as decoding channels don't have any extra buffers involved).
So your setup will the look like this:

Player1 (decoding) ----> Mixer1 ----> Soundcard (FRONT)
Player2 (decoding) ----> Mixer2 ----> Soundcard (FRONT)
BufferStream         ----> Mixer3 ----> Soundcard (REAR)

When you want to PFL either Player1 or 2 you simply create a BufferStream DSP instead of the StreamCopy and then add the BufferStream to Mixer 3 as a source.

There is only one problem: I´m not able to insert the BassMix into my code. Is it possible that the BassMix V2.3.0.1 is not supported in BASS.NET 2.3.1.8? I get a MessageBox with: "Incorrect Bass.DLL version (2.3.0.3 is required)"

However, I think I will wait till 2.4 release because if I insert BassMix I have to change nearly everything in my Class...

All in all I say thank you very much, or in good old german Danke für die Hilfe, das könnte ich ja sowieso besser als das englische Zeugs...

Hi radio42

Thanks for your reply.

I have to explain my configuration first. I wrote a class called BassControl. There I initalize Bass and all the other things I need. I have 3 players -> 2 independet players to mix my sound for the PA. 1 player for monitoring, for example pre-listening. All players can be switched to different outputs, for example Player1/2 SpeakersFront and Monitor to SpeakersRear. Now I have a button to switch the running Player1 to Monitor. For this I use the DSP_Streamcopy. The problem is now the delay but also another. If I want to switch both running Player1/2 to Monitor it doesn´t work.

Thats the code which I call for Player1-Monitoring:

player1.Monitorload(playerMon.Speaker, playerMon.Device)     // playerMon.Speaker/Device returns the number of the device/speaker
player1.MonitoringStart();

public void Monitorload(int _speaker, int _device)
{
      streamcopy.StreamDevice = _device;
      streamcopy.ChannelHandle = streamFX;
      if (_speaker == 1)
          streamcopy.StreamFlags = BASSStream.BASS_SPEAKER_FRONT;
      if (_speaker == 2)
          streamcopy.StreamFlags = BASSStream.BASS_SPEAKER_REAR;
      if (_speaker == 3)
          streamcopy.StreamFlags = BASSStream.BASS_SPEAKER_CENLFE;
      if (_speaker == 4)
          streamcopy.StreamFlags = BASSStream.BASS_SPEAKER_REAR2;
      if (_speaker < 1 || _speaker > 4)
         return;
}

public void MonitoringStart()
{
    streamcopy.Start();
}


public void MonitorBufferClear()
{
    streamcopy.ClearBuffer();
}

I have thought about BassMix to realize this feature but I don´t know if BassMix is the right thing for that??

Thanks for your answer.

The StreamCopy DSP actually uses an internal buffer - which might cause the delay.
So you might call the "ClearBuffer" method when changing the position etc.

It helped a little bit, but it isn´t perfect. I have a delay for some ms to let me guess 300ms.

However, a more efficient DSP to clone a channel might be the newer "DSP_BufferStream".
So you might try this one as well.
This DSP was added in a later version of BASS.NET and due to compatibility reasons I didn't remove the StreamCopy DSP.

I have looked at DSP_BufferStream, but there I have problem to say which Speaker I want to take. StreamFlag is only a "getter". Maybe I don´t use it the right way but I have no idea how to initialize for speaker. I need that because I´m playing a stream on PLAYER1 and with streamcopy i want to copy 1:1 to another MONITORING channel (headphones).

Thanks for your help

Hi all

I´ve added a streamcopy DSP Effect to my soft and it works great. The sound is correct as long as I don´t change the position. If i change the position or ChannelPause() or even after a Stop() --> Play(), there is a delay of 1-2 sec.

Then I have to resest the streamcopy and it works again. Changing Tempo or Pitch does not cause a delay.

Maybe someone has an idea...

Thanks MB

Hi lab82

Don´t get me wrong, but you should learn C# programming first...

If you haven´t got the basic skills it makes no sense...

MB

Hi lab82

Install http://www.un4seen.com/filez/4/Bass23.Net20.zip and be happy. There are many examples inside...

Hi Xire

Where can we downlaod the file?? Maybe I´m to blind to find, but could you post the Link...

MB

Check out "Utils.FixTimespan(single, string)" in your help. It returns a string in many different formats.

MB

my own Splash Screen doesn´t solve it, so I also don´t know what´s the difference between yours and mine *gg*. But Ok, the soft is running and that´s the most important.

Thanks again...

MB

thank you for reply...

...I´ve changed my graphics to

dev.TextRenderingHint = System.Drawing.Text.TextRenderingHint.ClearTypeGridFit;

and now it works fine. Could it be, that your splash screen changes the defult settings? But why do I ask, the problem is solved and so i say thank you very much.

Hi all

I´ve written a small DJ-Prog under C#. My Bass.Net wasn´t registered till today. Now I have some Problems as you can see in the following pictures...

So it look like when Bass is registered:




and so without registering:



As you can see there is a font problem. I don´t know why, I only have to remove the Registartion Code and everything works fine. The text is written on a Panel.

Has anybody an idea how to solve this problem?

This is the code for the registration: BassNet.Registration("mxxxxxxxxes@gxx.at", "2X22828xxxxxxx"); I think that should be OK, am i right?

thanks for help
