We are interested in buying Audio Sound Recorder library to implement recording and playback functions in our Vb.Net application.
We have some questions about it:
- With an appropriate "Y-cable" connected to a Line-In Stereo PC Input, we would like to record two mono audio sources into two separate audio files, one for Left Channel and one for Right Channel. Audio signal, is not necessarily present on both channels, then, they must be considered and recorded as two independent channels. Is it possible with your library?
- Has library any "crypt-decrypt functions" so that the recorded audio files can be played only by the library and not by standard players (WMP, Winamp, VLC, ecc.)?
- Does your library support multithread for multi audio source recording at the same time?
I apologize in advance for my bad English
Yours faithfully
Matteo
Hello Matteo,
below the answers to your questions:
- the component comes with a set of methods having the prefix "StartSplit..." like StartSplitFromDirectSoundDevice and so on: these methods have the capability to split the two channels into two different output files.
- the component comes with encryption/decryption capabilities: see the tutorial "How to protect your recording sessions through encryption" for details:
http://www.multimediasoft.com/asrecnet/help/how_to_protect_your_recording.htm (http://www.multimediasoft.com/asrecnet/help/how_to_protect_your_recording.htm)
- multithreading is implemented internally to the component: if you want to record from different sources at the same time, you should create multiple instances of the component inside the same application, one for each recording session.
If you should have further questions, please, feel free to ask :)
Kind Regards

Hello Severino,
...and Thank you very much for the prompt reply.
I'm downloading your demo library to test it.
- About the capability to split Left and Right channels into two different output files, I suppose, a single "Recorder - StartSplit" object handles audio input on both channels.
In this way, will be always generated two files when audio signal is only present on one channel, and I can't manage Left and Right channels as independent channels.
Is it correct? - With Audio Sound Recorder for .Net, can I record mp3 files directly?
- About license...In company where I work, I will be the only developer that will use your library; can I use a single license for multiple projects?
Thanks again
Kind Regards
Matteo
Hello Matteo,
you are welcome.
- yes, you are correct: if one of the channels should not produce any incoming audio a file containing silence should be generated. At this point you may simply decide to delete the silent file at the end of the recording session.
- yes, you decide the output format before starting the recording session and the multimedia engine will route incoming audio data to the correct encoder (Lame.exe for MP3): see the "How to perform a recording session" tutorial for further details:
http://www.multimediasoft.com/asrecnet/help/how_to_recording_session.htm (http://www.multimediasoft.com/asrecnet/help/how_to_recording_session.htm)
- yes, the product's license is "per developer" and not "per application"
