Could you be so kind to report me the exact version of the Btn3Dmms64.dll installed on your PC? Please, verify also if you have some other instance of the DLL installed somewhere else because it's likely that there could be a versioning issue of a newer version of Ctl3dMagic.dll referencing an outdated version of Btn3Dmms64.dll

Hello,

Windows updates are sometime buggy themselves and this seems to be one of these cases; probably something was deleted inside the registry because, being DirectX stuffs implemented through COM classes, it's likely that the CLSID identifying the class of the effect was removed in error: let's hope that this will be fixed soon by Microsoft.

Kind regards

Hello and thanks for your feedback.

Indeed it seems that something was broken inside DirectX because it currently returns an error stating that this special effect is not available: we will investigate the issue further and will let you know our findings.

Hello,

the default algorithm for automatic BPM detection, the one that reports current song BPM through the BPMAvailable event, is based upon the SoundTouch open source library and it's actually certainly not optimized for all of the genres and should be mainly used with techno and disco music; anyway keep in mind that sometime this kind of algorithms can detect a x2 so there could be the need to divide the result by 2 as probably in your case.

We have also another undocumented algorithm which can be invoked by calling the undocumented method BpmDetectionTypeSet passing "1" (without quotes) as parameter: you could try to see if you obtain better results with this algo.

You can in any case upload the song file for evaluation to our FTP server:
ftp server: ftp.mmsoftlabs.com
username: myguest@multimediasoft.com

Once uploaded, please, send me a note so I will download it.

Hello again,

a possible solution to your problem, allowing to operate as a source for multiple mount points from a single application, would be to avoid using the WASAPI protocol and to use the default DirectSound protocol, allowing to create multiple custom stream mixers and to cast each of them to a separate mount point.

For this purpose we have created a small sample which shows how to operate; you can download it from the link below:
https://www.multimediasoft.com/tmp/Sample.zip

Before using this sample it's recommended that you download and replace again the multimedia engine in order to avoid a small bug that was found while creating the sample.

Hope this helps.

Kind Regards

Hello,

thanks for your feedback.

It's likely that you are not using the stream mixer and the casting in the correct way: when using WASAPI, a single stream mixer, in this case the internal stream mixer that serves as the output of the sound card, can only serve one casting (mount point) at a time: if you use the same stream mixer for more mount points, only the last one will effectively work. This behaviour is by design.

As you noticed, this doesn't happen when using a player so you could have more than one player, each linked to a different casting session.

Hello again,

after further investigation we have found the nature of the original issue and we have reverted the code in order to use again the internal encoders for casting purposes so there would be no more need to use an external encoder: we suggest to download again the multimedia engine, using previously provided URLs, and see if the new build fixes the problem on your side as well.

It would be very kind of you if you could report us if the updated version is enough to fix the reported issue.

Hello,

as recommended inside the documentation tutorial "How to use the control as a source for streaming servers like SHOUTcast" https://www.multimediasoft.com/adjstudnetapi/help/adjstudnet_000076.htm
and inside the section "Files to be included with your application"
https://www.multimediasoft.com/adjstudnetapi/help/adjstudnet_000002.htm
in order to encode certain formats (like MP3) for ShoutCast and Icecast servers there is the need of an external encoder (Lame.exe, etc.).

It must be remarked that inside the previous versions we tried to use an internal encoder that seemed to work well but, unfortunately, it seems to give the problem you reported so we reverted back the behaviour to the usage of the external encoders as specified inside the documentation while we will investigate the problem further.

A copy of the needed encoders should be already available inside the "\Windows\System32" folder of the PC where you originally installed our setup package.

Hope this helps

Kind Regards

Hello,

we have been able to replicate the issue so we made a slight modification to our engine. You can get the latest build of the multimedia engine from the link below:

https://www.multimediasoft.com/bins/AdjMmsEng14.zip
and you can use it to replace existing instances on your PC under the following folders:
* C:\Program Files\MultiMedia Soft\Audio Sound Suite API for .NET\Audio DJ Studio API for .NET\Redist
* C:\Program Files\MultiMedia Soft\Audio Sound Suite API for .NET\Audio Sound Recorder API for .NET\Redist
* C:\Program Files\MultiMedia Soft\Audio Sound Suite API for .NET\Audio Sound Editor API for .NET\Redist
* If your machine has a x86 version of Windows
  - C:\Windows\System32
* If your machine has a x64 version of Windows
  - C:\Windows\SysWOW64

The x64 version is available as well on the link below:
https://www.multimediasoft.com/bins/AdjMmsEng14_64.zip
and you can use it to replace existing instances on your PC under the following folders:
* C:\Program Files\MultiMedia Soft\Audio Sound Suite API for .NET\Audio DJ Studio API for .NET\Redist
* C:\Program Files\MultiMedia Soft\Audio Sound Suite API for .NET\Audio Sound Recorder API for .NET\Redist
* C:\Program Files\MultiMedia Soft\Audio Sound Suite API for .NET\Audio Sound Editor API for .NET\Redist
* If your machine has a x64 version of Windows
  - C:\Windows\System32

It would be very kind of you if you could report us if the updated version is enough to fix the reported issue.

Hello,

looking at the properties of the 2 streams, it seems that the first one has a bitrate of 128 Kbps while the second one has a bitrate of 96 Kbps: please, try to reduce the one sent by our sample to 96 Kbps, using the connection Settings form accessible through the "Settings" button, and see if the problem persists.

Kind regards

Hello,

unfortunately this doesn't help because we cannot understand the exact point of the code where the application crashes.
In any case we have made a slight modification to our engine in order to avoid a potential issue when the connection to your test url fails. You can get the latest build of the multimedia engine from the link below:

Hello,

we have tried several times to connect and, as you reported, most of the times the connection fails.
When the connection fails, by reading the URL directly, in a few cases we have got back an error message that the icecast connection reached its limit, in other cases we simply get back some stream of bytes without any useful information.

Unfortunately, in no case we experienced a crash so at the moment this doesn't allow us to understand its nature. If you could launch the InternetRadio.exe sample in debug mode from Visual Studio and get the call stack of the crash we could probably have a better understanding of the issue.

Hello,

please, provide a valid URL that we can use to perform some testing in order to reproduce the issue.

Hello

There are two ways to send an audio stream to a streaming server. The sample project is one of them.
But it still needs to be attached to a Player and then output.
Is there any way to capture only the input audio source but not play output?

Yes, you can avoid any sound being sent to the render device by setting its output device to -1; inside the FormMain_Load function you will find the following lines of code

Code Select Expand

// obtain the stream mixer internal to the selected WASAPI device
m_nStreamMixerUniqueID = m_audioDjAPI.StreamMixerGetIdFromOutput (m_nWasapiDevice);

simply add the following code immediately after them:

Code Select Expand

m_audioDjAPI.StreamOutputDeviceSet(m_nStreamMixerUniqueID, -1);

There is one more thing that I am confused about the WasapiMixAndClone sample project.
Why a control can initial more than 4 players? The three extra Players in the sample program seem to have no effect.

// init the DJ Studio control by instancing an adequate number of players:
// 2 for playing sound files from disk and 5 for attaching input devices
short nPlayers = 2 + 5;
nPlayers = m_audioDjAPI.InitSoundSystem(nPlayers, m_nWasapiDevice, m_nWasapiDevice, m_nWasapiDevice, 0);

Inside the project there are 2 players that are used for loading and playing sound files from disk (Player_1 and Player_2) while the other 5 players (Player_Input_3 up to Player_Input_7) are used to attach different input channels and mix them into the internal stream mixer of the render device.
If you shouldn't need to play sounds from files on disk and you should simply need to attach and cast one single input stream you may instance one single player only.

Hope this helps

Kind regards
