Recording an Audio Input stream using CMdaAudioInputStream

[rastapasta]

Can Anyone help.

I have created an application that uses the CMdaAudioInputStream to record an input stream to a file.

1. What is the default file format i.e. is it PCM, WAV or AMR.

2. How can I set the file format that I want to record too. And if, for
Example PCM is the default format, what should I do to make my
application record the audio input stream to the WAV or MP3 i.e
different file format.

3. How do I continiuosly stream audio input. I have looked at the Audio
Input/Output Streaming example which is good. but has limitations for
what I need to do. I need to Record approx. 5 - 10 mins of audio data
if possible.


Thanks in advance

its PCM, you basically just have to use converters to convert the PCM to your target format after you get it from the recording stream.

Mr. Rastapasta
please i need help urgently
iam a student and have no idea about symbian, and was asked to make a digital signal processing DSP project on S80
please view my thread and this thread too
no one answered my questions on them
i hardly could (killed myself to do this) make my CMdaAudioInputStream but i couldnt compile my code due to these errors:

HELLOWORLDBASICAPPUI.obj : error LNK2001: unresolved external symbol "public: void __thiscall CMdaAudioInputStream::SetPriority(int,enum TMdaPriorityPreference)" (?SetPriority@CMdaAudioInputStream@@QAEXHW4TMdaPriorityPreference@@@Z)

I have created an application that uses the CMdaAudioInputStream to record an input stream to a file.

so please tell me what's wrong, and please as fast as possible
my trial (my bad code ) is written in my threads

I have looked at the Audio Input/Output Streaming example which is good

where is that example??



many thanx in advance
