microphone

Is there a component or code that allows the following: Record a spoken word (or words) and save it/them to a file that can be played back. The file must be able to be played back on XP, Vista and Windows 7. The file can be either stand alone or saved to a datasource. [Using Delphi 7 for creating apps on XP and using Absolute Database.] The functions in MMSystem.pas let you do this using Windows API. You can either use high-level functions such as the MCI functions and PlaySound , or low-level functions such as waveInOpen , waveInPrepareHeader , waveInProc etc. If you want high control, you

I'm working on Audio tuner application in order to tune musical instruments. User should play a note, then in my application I should show which frequency it has. The first, I should access to microphone? AudioRecord recorder = new AudioRecord(MediaRecorder.AudioSource.MIC, sampleRate, AudioFormat.CHANNEL_IN_STEREO, AudioFormat.ENCODING_PCM_16BIT, bufferSize); Then I need to calculate frequency of sound. How can I do this? TRManderson I'm also trying to do this. I haven't managed it myself yet, as I'm completely new to android development, but here are two useful links to the source code of

I want to develop a small Android app to measure the current noise level (probablyin dB). But I have no idea what to look for in the libs. I don't want to record the noise. Can someone give me a pointer what classes to look at? I recommend looking in these classes: android.media.AudioFormat android.media.AudioManager android.media.AudioTrack We used them in the Blinkendroid audio package a short while ago. soul For me ' maxAmplitude ' was not helpful. After day of researching I eventually reached my target. You can find my solution here: Android: AudioRecord Class Problem: Callback is never

I'm trying to access sound volume data from the microphone in realtime. I've tried AVAudioPlayer but it only monitors sounds from a source like an mp3 and not from a microphone. I've also tried The SpeakHere app but it's proving to be much tougher to understand with all the Objective C++ syntax (i'm a newbie). Is there another class similiar to the one in SpeakHere but written only in Objective C? Erik B sc_listener is deprecated. The correct answer today is to use AVAudioRecorder . This tutorial explains how to use it. Erik's answer is correct. Here is a reusable implementation using this

in my application, I need to direct sound from microphone directly to speaker. No other actions. I found a way to direct sound from microphone to earpiece by playing a file and setting speaker off. So I guess speaker can work similarly. However I don' know how to get rid of the playing file thing. Thank you. speaker() { m_audioManager = (AudioManager)getSystemService(Context.AUDIO_SERVICE); m_audioManager.setSpeakerphoneOn(true); // not needed I think //m_audioManager.setRouting(AudioManager.MODE_NORMAL, AudioManager.ROUTE_EARPIECE, AudioManager.ROUTE_ALL); earpiece need this?
