I am streaming an MP3 audio and instead making this MP3 audio to play, I want it to be converted to PCM format and pass this PCM audio to AudioTrack(as it takes PCM data as input.) instead of passing my MP3 stream to MediaPlayer. Can anyone please help me to convert the MP3 to PCM stream?

Is there a way to determine the audio format of an audio file in Android? On normal java I do it like this:
File file= new File(...);
AudioInputStream stream = AudioSystem.getAudioInputStream(file);
AudioFormat format= stream.getFormat();
I have a couple of videos, that I would like to strip the audio from, and was planning to use FLAC, and/or similar lossless codec; but before I do this, what codecs can Andriod decrypt? According to Android Central, it can decode FLAC, but only in Android 4.0 and higher, and I'm currently on Android 2.3.4 on a HTC Amaze 4G...
Is there any software I could get, in order for it to decode/decrypt FLAC correctly?
I don't mind using any other lossless audio codec, as long as Android 2.3.4 supports it...
Does such a thing exist please folks - want to rip some audio for an mp3 ringtone from a comedy video clip

View 1 Replies View RelatedAccording to the MS website, Windows Media Player queries an MTP device to see what formats it supports. My Razr Maxx HD supports ogg and m4a. When attempting to sync WMP does not sync those files stating they might not be supported on the device. Being that I've had so much trouble in the past even getting any of the Android devices to be properly detected as an MTP device I'm worried this is a driver issue.I should be able to get WMP to at least convert them.
this is the device mis-reporting the formats, Windows not querying them properly, or an actual WMP issue? Would like to be able to get sync working without any conversions. Maybe there is a way to hardcode formats within the mtp inf file?

My application cannot handle the JNIE overhead, as I need to make 2 JNIE calls to the native C/C++ code for every 20msec. So I am trying to use the native media libraries and the realted C/C++ files provided by Android in the folder "//external/srec/audio/test" of the donut build. Ex. AudioHardwareRecord, AudioInRecord etc.. I am implementing all the calls in the native layer.
I am using the sampling rate as 8000 and want to read 160 samples (320 bytes) at a time.
I used the following values to create the AudioRecord..
CODE:..........
It says "success" after creating this interface but I am getting the error "Bad Value" if I am doing the InitCheck.
And it is crashing once I start reading the samples or if I try to retrieve the configured sampling rate.
Has anybody tried to access this native code?

View 1 Replies View RelatedIs there an Android equivalent to the iOS Core Audio / Audio File Stream Services? I need to be able to read audio bytes from a network and feed them to the audio system under my control, so I can do my own timeouts / reconnects / range requests / etc. without interrupting the audio playback (since the system audio thread would be playing audio already enqueued). It seems that MediaPlayer doesn't give me this level of control. Is there a lower-level framework that does, either in the SDK or NDK?

I have used various programs from HandBrake to Sony and I can get audio with no video (mp4). I can get audio with still image video (wmv). The DI seems very picky as to which videos it will actually play back. Is there a recommended way to convert my videos / DVS into a format the DI can play?

RR is 2010.
I want to develop an app that lets one intercept raw audio data sent for playback (possibly by a different app), and apply audio enhancements over this raw data.Does Cupcake allow such filtering of audio data? If so, which API should I use? I understand this may not be possible at an application level for security reasons.I'm trying to see if this is possible with native code linking to public or private API of Android.

View 7 Replies View RelatedFirst of all, sorry for my bad english. I'm new into Android application development, just experimenting with the emulator and the SDK. I have searched with some keywords on the developer group, but i didn't find what i need. I'm searching for classes which with i can do simple audio DSP on locally stored audio files. e.g. i like to do crossfade/overlap on MP3 files, and an overall automatic gain control/ equalization on the realtime mix . As i see i can use the AudioTrack class to send raw PCM data to the audio hardware, so i could implement the DSP in java, but i don't see any way to use the internal decoders to grab decoded PCM frames from encoded audio files (like MP3, OGG, AAC). I thought about using Java decoder implementations like JLayer to do the decoding but that's a very CPU intensive approach which is not good for e.g. a media player application which runs in the background. Is there any classes for using the platforms builtin decoders, or should i "port" some available decoders with NDK to my application?

Can someone please tell me how to do this?
View 5 Replies View RelatedI've been trying to understand how to get data about all the audio files in the device using MediaAudio but unfortunately the documentation is far from clear. Also, thereīs almost nothing about it on the forum right now and I couldnīt find good resources over the internet.
Iīve seen pretty quick and objective examples on how to access the main information from the containers but I couldnīt find in any place how I could get the names of the tracks (MediaStore.Audio.AudioColumns doesnīt have an specific constant for it) and the most important, how I could retrieve the path for the media (audio file in this case) Iīve found using the info on MusicStore.Audio.
am I missing something here? It seems it should be so easy but I canīt find the info! Also if I change any data on the container, will this data be also changed in the real file as well?

I have searched the whole group but wasn't able to find a answer for my problem.I want to record audio from the microphone, apply some audio signal processing and than save the processed audio data in a compressed format.I figured out, how to record audio uncompressed but now I wonder if I can use some api functions to store this data in a supported compressed format.
