I have an .avi file with a 5.1 audio stream, but the stream is messed up - most of the sound is coming out of the FR channel, because it was improperly encoded from a mono or stereo source. I can watch the video ok on a pc if I use gomplayer and set up AC3 decoder to downmix to mono - the audio from all channels is mixed and played through L and R channels of headphones.
The Question is:
Does android have an app or a plugin to downmix to mono audio, for Nexus 7?
I know Voodoo control panel can do this, but it doesn't work with N7.
I also tried a number of players -
mx player, mobo player pro, moboplayer, dice player, vplayer, rock player lite, bs player. There may have been a few more I don't recall at the moment.
None of these players have the option to downmix to mono.
Can anyone help please?
Thanks.
Forgive me, I'd like to bump the thread to see if anyone knows of a more elegant solution.
Try DSP Manager's Headset Virtual Room Effect and select a room type that sounds best for you. I am deaf in my left ear so I needed all my audio downmixed to mono and this did the trick.

How does choosing one of the Virtual Room Effect options downmix the sound to monaural? And which option does downmix to mono?

I too would love mono mix sound!
Stereo-to-mono effect on Windows PC and Android
First of all, a free audio-player app called AIMP on Google Play, Android, has a Settings -> Sound -> Output -> "Mix to mono" setting, which will be useful for this need.
Secondly, while I don't know which Android app he's talking about, edditnyc is most probably right, because on a Windows PC, and depending on the sound card, you can right-click the speaker icon in the system tray (bottom right corner), click Playback devices, right-click Speakers, click Properties, click the Enhancements tab (if it doesn't exist then perhaps the sound card doesn't support the feature or the latest drivers for the sound card aren't installed), scroll down and tick Headphone Virtualization. And while this does not downmix stereo or others channels to mono, it does something that emulates this effect of mixing stereo to mono on the PC; it allows you to hear sounds that are originally only playing on the left speaker, for example, on the right speaker. And to the best of my knowledge, this should work with all sound that plays from any program on the computer, including audio players, video players, and games.
Hope this helps those who need this for technical issues or for unilateral hearing loss, at least until Microsoft and Google start to recognize this need in their accessibility settings.
I'm experimenting with writing an app that uses AudioTrack to play audio (for purposes of testing, sine waves generated within the app) from my Verizon Samsung Galaxy Note II to my ESI U46XL USB audio interface. It works perfectly in stereo mode, but when I initialize AudioTrack with CHANNEL_OUT_5POINT1 and attempt to feed it a 6-channel stream, the sound that plays back doesn't sound anything like that stream.
I'm suspecting that the USB audio driver is the problem, since anything higher-level would also impose its limitations on the HDMI audio, wouldn't it? Google says that "Android 4.1 supports multichannel audio on devices that have hardware multichannel audio out through the HDMI port." But can anyone confirm my suspicion? I was also thinking maybe the 16-bit interleaved PCM format isn't used for > 2 channels, but I've tried every other format I can think of with no luck.
I'm hoping the problem is anywhere except for the USB audio driver, because then I can bypass whatever it is one way or another.
Hi ,
When ever I try to upload a video which I recorded on my phone and try to play it on Facebook/Instagram/WhatsApp the sound comes outs as a constant hissing noise like a TV with no signal.
I used the manual video mode to record the videos.
Is there a reason why it's doing it ? I just noticed on Auto mode , the video sound works perfectly, just when recorded on manual mode it does this ??
When in manual check if it records audio in HiFi or normal mode in settings. If you record in HiFi then audio track will be saved in LPCM format which isn't supported by all sorts of web sites, so you must listen to it on PC at home and compress audio to whatever AAC codec suites best with plenty of free utilities, i.e. Xvid4PSP, mediacoder etc
Is it possible to record 24bit/196khz internal audio?
Is there any app that can do it?
Or is there any Windows program that can record audio from my phone's 3.5mm jack?
You can use the 7-day trial version of Adobe Audition to perform the recording.
You will need a cable to connect your 3.5mm stereo from your phone to your laptop's Line-in audio jack.
I am creating an android application that plays a beep sound whenever it detects a pre-defined sound. In another way, I have three drum/piano/vocal sequence mp3 file with me which is stored along with the apk assets. After installation, the three files moved to the internal memory. Whenever I play any audio/video in any of the video/audio player(eg:youtube/vlc) on my mobile, if the music sequence of the playing audio matches any of the already stored three mp3 files, Then a beep sound should produce. This is my aim. But I am hard to find such a library to compare music that is playing inside the mobile with another app. Google assistant and Shazam app just listen to audio from the mic and compare the audio. But in my case, I need to compare audio which is the playing device itself.
Note: The app will be running 24X7 by listening to the sounds played on the device. This application is not intended to build an unethical product. This is used for an industrial purpose.
If somebody needs more clarification, I will update the question
