convert to WAV to AMR on device - Android Apps and Games

Does anyone know if there's any Android App that converts WAV files to other formats like AMR or other compressed formats?
I know there's desktop apps for this but I'd like to do everything on phone.
Thanks for any info.

how to play wmv files?

Media player doesn't seem to read wmv files (at least the video part of the file). Any suggestion for a good replacement software?
try beta player
Media Player definitely plays wmv files, are you sure your wmv isn't corrupt?
I've noticed that Windows Media Player 9 on the Pocket PC is not capable of playing .WMA and .WMV of all bitrates, I'm not exactly sure which bitrates its not capable of, but try re-encoding your file to a different bitrate and try it again n the device.
To no1: the file is not corrupt, media player on XP reads it without problem.
To ZeroXtreme I'll try it. Thanks everyone

[Q] Best format for music, size and quality

Can anyone tell me the best format to store thier music so that the files will stay resonably small but retain thier quality. I guess what I'm asking is, is there a better file format than MP3? I was storing a ton of music on my old phone's SD card, but since the Nexus S doesn't have the "extra" room an SD card allows for, I was wondering if anyone can help me to shrink the files to save space.
Also, I know, I can just carry fewer songs, so please don't put that.
Thanks.
Man just chill
there are better formats, but i don't think the stock music app actually supports them.
The nexus s does have 13GB of space on the SD card, i think that would be enough unless your one of the crazy people who spent $100 on 32GB SD card.
So how big are your MP3 files? Encode your MP3 to VBR 128-192kbps, they sound fine with good file sizes. If you're an audiophille, you'll have your own standards.
AAC is the best format, because it's actually mp3's successor. They couldn't call it mp4, because that was already used for the video file format.
AAC uses a different compression algorithm, thereby offering better sound quality at lower bitrates. 96kbs AAC = 128kbs mp3 in terms of quality.
HE-AAC v2 is an advanced format of AAC that allows even lower bitrates, such at 32kbs.
Listen to this song encoded at 32kbs: HE-AAC+v2 (44100Hz [email protected]) 1.1 MB
Yup, the entire song is 1MB!

pretty awesome stuff there, do the android music apps support it though? stock, winamp, poweramp?
I am making a batch file that will automatically transcode any mp3 files in the current directory to HE-AAC v2 mp4 files. All you'd have to do is unzip it, copy the .bat file into the directory where your mp3 files are, then double-click the .bat file. I have it set for 64kbs for highest quality.
There are players available that will play AAC files in android, just search the market.
Also, make sure you edit the .bat file paths to the correct path of lame & neroAAC.
Code:
SET LAMEEXE="C:\Users\Administrator\Desktop\AAC\lame.exe"
SET NEROAACEXE="C:\Users\Administrator\Desktop\AAC\win32\neroAacEnc.exe"
doubleTwist supports mp3 AND AAC, and it's free
If you're really concerned with file size, 32 kbs is the lowest I would go and 48 kbs is a nice balance of size and quality.
I use ogg vorbis 192kbps which can yield very good quality sound, especially Android has native ogg support.
OGG Vorbis has been consistently proven to yield higher quality audio at lower file sizes than mp3, and about equal to or better than AAC. That's why it's part of Google's WebM video container format. Vorbis is supported by default in Android and is what I encode my music in (along with FLAC).
Windows doesn't support *.ogg by default (open standards aren't their thing), but this link should get you set up to listen on Windows: http://www.vorbis.com/setup_windows/

Ogg is better than mp3, but it gets hard to tell difference between formats once you get to 320kbps. Being open source, ogg benefits from improvements over the years while mp3 is stagnant and costs to include on device. But its well adopted and almost everywhere. Other formats may be better compression, but not well supported like mp3 and ogg.
Bah! No URLs for newbs. Google for: winamp preferences guide, and on that wiki page search for the text "force transcoding"
I was looking into writing an auto-transcode app/script for just this reason, but it turns out that winamp has one built in: I set the "Force transcoding of compatible tracks if bitrate is over __ kbps:" to transcode anything above 191kbps and when syncing music over it works like a charm. You can set it to a couple different codecs, winamp seems to include LC-AAC, AACPlus, mp3, and wav.
Note that these settings only appear when you have your device attached.
Each MP3 averages to about 3-4mb. I only have about 4gb worth, so not a lot, I'm just looking to obtimize space where I can. Is there a specific AAC player for Android that you would recommend?
Oh yeah, and thanks for the helpful answers.
If you care about audio quality you wouldn't use mp3 any way.
Use 160 its the best middle ground.
Un compressed aiff is best but 10MB per minute is to big for a phone

WMA Audio
Nexus S doesn't play wma audio ? If it does let me know how.
Thanks
Im a big advocate of FLAC but size compression is almost non existent
All my music is in mp3 format and I was just discussing with my brother how to improve sound quality. I went to the vorbis site and downloaded "audacity" a free audio converter.
I chose a mp3 file I had which was about 10mb @ 320kbs. Using audacity I exported that mp3 to .ogg and it cut the file size down to 4.2 MB @ 165kbs. Does that sound about right? Does doing a simple export actually improve sound quality? Or just cut the size down.
EDIT: I did some more digging around and apparently converting to ogg from mp3 is not recommended rather to convert to ogg from a lossless format like flac or from CD.
Sent from my Nexus S using XDA App
320kbps is damn near lossless, you won't get much more quality from a lossless format.
Use I tunes to convert your music. It does a great job. mine is 192kps. Just about right for me for mp3. I'm just use to mp3. I will try ogg

havent really tried myself but has anyone tried the leaked music player to see if it supports any new formats?

[Q] Video Encoding in android

Hi all
I want to develop an android app in which i want to encode a video in mp4 format from series of images and a mp3 file.
I successfully created a video in mp4format from series of images by using JCodec library.
but unfortunately i'm unable to encode a mp3 file in it because JCodec does not have functionality of mp3 merging in mp4 along with series of images.
After that I also tried FFMPEG but i was unable to compile it.
So please help me to sort out this problem.
Thanks

[Feature request] External audio-streams

Please add to API ability to pass additional audio streams for video file in similar way as it done for subtitles.
sample: I have on server mp4 video file with 1 audio stram and couple mp3 files with audio in other languages.

I'd love this feature too. Especially for playing videos that have the audio and video tracks already separated (eg. m4v and m4a files of the same name). Ideally in this case the app could detect that the video file had no audio and then pick up the similarly named audio track and play that.
yes, this is the MOST WANTED feature I need for MX Player (or Pro).
I got a huge movie collection in MKV files, many of them are not packed with my native language audio stream and my littlle child is too young to read subtitles, actually I can get the native autio stream perfectly match these movies.
so now I have to repack these MKVs to enable the audio selection in MX player, this will change the original files that I cannot continue seeding them
--------------------------------------------
edit: and the external audio stream files may in the file type of MKA, DTS, AC3, etc.

Exporting the High-Res audio from videos?

Hi, im having the following issue when trying to share the videos i recorded with my HTC U11, hope there is some fix for this.
I recorded a video with High-Res and the only way to share this video is with .mkv format, but the video needs to be edited and when is imported to Premiere there is no audio, neither if i convert the video to mp4 with media encoder, also tried to convert with VLC but no success.
Is there anyway or option that i missing to either extract the audio and insert it on a mp4, or convert the entire video to mp4 with audio?
Thanks.
Try media converter by antvplayer.
