Last post by Administrator - September 26, 2024, 05:32:32 PMHi Terry,
this issue should have been fixed inside the latest build 14.4.2.1 of the multimedia engines AdjMmsEng.dll and AdjMmsEng64.dll.
You can update your installation by uninstalling the current version and by downloading the latest setup package available on our website.
Hope this helps.

Audio playback and audio management components / EV_SOUND_DONE infinite loop
Last post by Terry - September 26, 2024, 07:39:25 AMHi,
I tried to load a sound file from the website through the "m_audioAPI.LoadInternetStream(0,"http://localhost/test.mp3")" command.
When the playback is completed, the EV_DOWNLOAD_COMPLETE event will be triggered first, and then the EV_SOUND_DONE event will be triggered infinitely.
The execution logs is as follows

Last post by Administrator - August 30, 2024, 06:53:19 PMHello,
the main error is caused by the fact that you are not passing the correct file pathname to the PlayListAddItem method. Try to change the following code
with the following code:
Another problem is the fact that you set the following code inside the handler of the enumPlayerEvents.EV_SOUND_DONE event, causing the playlist being stopped after the first song
please, move that line inside the handler of the enumPlayerEvents.EV_PLAYLIST_DONE event instead.
Another important point: The original source code of the Visual Basic.NET version of the PlayerCmdLine project (so also your code) contains the following line:
Be sure to replace this line with the following one or your application may experience several malfunctions
Hope this helps.

I discovered that the AudioDjStudioApi cannot play audio files in a playlist within a command line program.
I modified the sample program "PlayerCmdLine" so that the program can load a directory containing audio source files and play them, but it seems to be unsuccessful. It can load a single audio file and play but a playlist. The program code is as follows. Is there anything I'm missing?

Audio recording components / Re: Obtaining total record tim...
Last post by Administrator - May 08, 2024, 10:00:13 AMHello, you are welcome.
In this case unfortunately no specific event is available but you may obtain the total duration by applying a couple of arithmetic operations:
- in "Insert" mode you can simply add the duration of the previous session, which can be obtained through the RecordedSound.GetDuration method, to the duration of the current session as reported by the RecordingDuration event
- in "overwrite" mode is a bit more tricky because you need to keep count of the overwrite position and add to this position the duration of the current session as reported by the RecordingDuration event:
a) if the result of this sum is smaller than the duration of the previous session, which can be obtained through the RecordedSound.GetDuration method, then the total duration is still represented by the value returned by the previous call to the RecordedSound.GetDuration method
b) if the result of this sum is higher, then the new total duration will be the sum between the overwrite position and the duration of the current session as reported by the RecordingDuration event.
In both cases, please, keep count that the RecordedSound.GetDuration method needs to be invoked before starting the recording session or it will return the error ERR_RECORDER_BUSY (-64).
Hope this helps.
Kind regards

Last post by mjividen - May 07, 2024, 03:39:19 PMThanks for the answer. My problem is not APPEND but is displaying the total recording length in INSERT and OVERWRITE modes. (I'm writing code in VB on Visual Studio).
