for a school project I am trying to make an android application that, once started, will perform a spectrum analysis of live audio received from the microphone or a bluetooth headset. I know I should be using FFT, and have been looking at moonblink's open source audio analyzer ( http://code.google.com/p/moonblink/wiki/Audalyzer ) but am ...
I'm attempting to add the ability to use Bluetooth Headsets and Headphones to an application. I've modified the AudioSession like so: UInt32 audioRouteOverride = kAudioSessionProperty_OverrideCategoryEnableBluetoothInput; AudioSessionSetProperty ( kAudioSessionProperty_OverrideAudioRoute, sizeof (audioRouteOverride), &aud...
As far as O know, web pages play mp3 sounds by embedding invisible Flash players. Since Flash is not available on mobile webkit (iphone/ipad), how is it possible to play mp3 on this platform? ...

There are a lot of audio-resampling libraries available. My favorite in Secret Rabbit Code. Audio resamplers keep the correct frequency of the resampled signals, so a 4KHz sine in the source, will remain a 4KHz sine in the destination. This time, however, I need to resample a sampled IF/RF signal. The sampled signal contains data orig...
I started tinkering around with HTML5 recently and am very interested in Audio tag. Though one thing immediately came to my attention, it appears that OGG is the only format supported in Firefox! I understand that this is because MP3 and other codecs are proprietary software and require a license to use. But how is HTML5 Audio (and Vid...

But I currently need a player that plays only sample of songs and not full song, like Itunes and this kind of player seems hard to fun thus far. Does anyone know of one?

I am looking to write an Arduino script that uses whatever audio signal is going to the speakers to create a physical visualization. The Arduino is connected to the windows machine only through USB, so I need to use USB to find out what is being sent to the speakers. How would I access this information? ...
LAST EDIT - TWO SIMPLE ANSWERS NEEDED. 1) I was able to get the code working with a URL (it's the code from one of the responses below). But my song is in a wav file. When I try to do File url = new File("---");, it doesn't work. Instead, in the stack trace (thanks for that tip!), it says "Failed to allocate clip data: Requested buff...

I am trying use JS to playback some sounds. What i want to do is have piece of music playing but after a certain time replace it with another audio file. I thought the most effective way would be to reuse the same audio object, but it seems to not kill the original sound so all gets messy. What is the best way to do this? My code is bel...
I finally got my sound clip to work in my java application. This is picky, but there's a minor pause between each sound loop. Is there any way to "merge" the two loops slightly so the sound seems continuous? ...

I'm trying to very quickly port over an html application with plays sound (with soundmanager2) to a native android app using WebView. From my research, I haven't seen any evidence that sound, such as mp3s, can be played via javascript or any other methods using WebView. My goal now is to quickly port over the html app and then eventual...
