MP3 Recording From Microphone

Nov 14, 2011

I am trying to record many small MP3 files from my computer's microphone. There are numberous examples using mciSendString Library "Winmm.dll" to record .wav files. I find the .wav quality to be lacking and I really want to record straight into the MP3 format rather than converting my .wav files.

Send Beep Through Microphone Input?

Nov 21, 2011

Is a way of creating a program (either in C(+,++,#) or VB.net) that would be able to send a beep sound through the same line-in that is being used for audacity (not stereo mix)?

I am trying to make a way of syncing up audio and video from 2 different programs, in a similar way that a clapper bored works in the movies.

Would there be a way of using a sort of microphone enhancement that could be created because they affect the microphone input?

Using XAudio2 To Recognize Pitch From Microphone?

Apr 3, 2011

I'm learning to play the Trumpet and thought it would be a great idea to write myself a flash card type program that would flash a note, pick up the sound from the microphone, determine the pitch, compare it to the note and evaluate right/wrong. For example, it puts a middle C on the screen, listens for a tone above the din and beeps or buzzes if the result is right or wrong.

Reading Pitch From Microphone And Comparing To Preset Note

Sep 30, 2011

I am rather new to VB and every now and then I get an idea of a small project I would like to work on to increase my skills. What I am trying to do is:
1. Input the sound from the microphone
2. Detect what pitch the sound is
3. Compare it to the pitch displayed

For example, lets say I was to have the button "Start". When start is clicked, a pre determined (Or possibly random) note is displayed through a Label for 5 seconds (Lets use C as an example). During this time, the user can attempt to match the note C. When the user sings through the microphone VB picks it up, detects what note the user is singing at, and then scores him over the 5 seconds based on the difference between his note and C. It would also be nice if I could display the volume of the microphone, but this is not too important.

Do you know the little graph which the Windows 98/XP sound recorder used to show? It used to show the pitch and volume of the sound which was being recorded. Like I want to get the data from that.

Basically, I will start experimenting this stuff by showing the volume of the sound entering the microphone in a label. And maybe the pitch too.

VS 2010 See If The Microphone On A PC Is Working Correctly By Utilizing The SpeechRecognitionEngine Class?

Nov 15, 2011

I'm trying to see if the microphone on a PC is working correctly by utilizing the SpeechRecognitionEngine class.I'm using the following

VB.NET
Dim RecognitionEngine As New SpeechRecognitionEngine(New CultureInfo("en-US"))
'Dim synth As New SpeechSynthesizer
'synth.SpeakAsync("Microphone")

[code]....

When I run this code, the microphone runs until it detects a sound. If the room is silent, it never stops. At least so much as I can tell so far.But I need a way to detect when it can't detect a sound within a specified interval.I looked on MSDN and all I could find was a property called, BabbleTime. I can specify a TimeSpan that will time out the speech recognition, but from that, I can't determine if it was the timeout that caused the code to continue or if it detected sound.
