camera audio quality

Is there any way to increase the audio quality when anything is recorded? I am getting 8000 hz. horrible. not sure about the bit rate, but still if that is changed audio would be alot better.
I used to have an iphon (hated it everyday) but when I hacked it and downloaded a video camera program, the picture was horrible the audio was recording at 44100 hz and the bitrate was 705 kbits/sec. only 1 channel but you should hear the audio because wow.
can anything be done with total commander??

Best DVD converter for louder audio?

Does anybody know of a dvd to mp4 converter that will allow me to increase audio levels?
The desire's external speaker is lacking quite a bit in terms of audio quality and loudness and films I have previously converted to mp4 via handbreak, although looking very good, are a bit on the quite side though the external speaker with max volume selected. I know the desire is capable of playing media slightly louder as most YouTube videos playback at a higher volume.
In the past, I have downloaded and tested lots of dvd converters for best playback on the HD2 but uninstalled them all as I found Handbrake to be the best for the HD2. I know that at least one of them did allow you to adjust the audio level but I can’t find it again.
The Desire has vey low media audio playback volume compaired to the HD2 so I need the audio volume level to be a bit higher.
Cheers
Jason

Can HandBrake's DRC (Dynamic Range Control) help you out at all? You probably need to normalize rather than just boost (or maybe compress and boost) otherwise you'd get clipping/distortion.

Thanks for the reply Rob, I have tried setting the DRC to 2.5 but it doesn't seem to make any differance.
I just wish I could get these files to playback at the same level as most Youtube videos playback.

(Request) JPK Froyo video 2-5 seconds long for testing

As stated in the title I need short video file download from those running on jpk. 1280 by 720. Daytime nighttime does not matter. Just playing around with codecs.

here you go

thanks a lot.
good to know that froyo brings mp4 with aac instead of eclair crappy 3gpp with amr. should be better for the concerts and loud environments now.

lol...When i first saw the video i laughed, i didnt read wat the op said, just the title...rofl

@idan - there is no significat difference with aac audio, the sound is still crappy when you record a concert.

Damn audio, totally ruins the recording/video experience with this phone...

It still is a great improvement, now I can just make a video, start AllShare and immidiately see the result on the big screen using my PS3. I always thought it was a shame to use this stupid 3GP container so I have to remux all the videos on my PC.
As for the sound: does the phone record from headset if connected? If yes, I guess this could be exploited to use a better microphone. The inbuilt one is meant for the phone function, obviously, and they just didn't add another for noise cancellation and video recording.

Fantastic. Now all we need is touch-to-focus in video mode.

another nice thing would be to be able to change the recording sound volume or some thingy that corrects its selve when you record loud things.

It is possible to record from headset but sound is still crappy. It's software problem.

The problem is with the mic itself, it is very sensitive, it would be great if there was an app that could monitor the input level of the mic and adjust de volume when its lower or higher than a certain threshold level, if not automatic at least manually.

Some kind of mic equalizer?

my bad it was always aac audio and not amr. by mistake i compared with old nexus video lol. only wrapper changed to mp4.

This is just a stupid iPhone function. Video recording auto-focus is much usefull and better when you shoot a video.

Any fix for sound quality???

As we all know the sound quality when you take a video is terrible... Is there anyway to edit the video to fix the sound, or is there something that can be done to have good sound quality when taking a new video???

Editing the video after its taken would be pointless, you can't increase the quality once its already recorded. The only thing I can think of is being sure to use the highest recording quality setting. I'm not sure if it helps the audio quality any though. We are limited my the quality of the microphone that comes with the phone.

High-pass filter on audio

Hi there, fellows HOX users,
There were several topics about HOX's poor audio quality when capturing video or recording through voice apps, but still, there weren't any solutions how to solve the lack of frequencies down below ~100-200hz.
I have experience working with sound production, recordings, so I know that these limitations are only made by software. In that case, there must be some kind of solution to improve audio recording quality and enjoy HOX at 100%.
I tried editing srs_global.cfg (found in /system/etc/soundimage) (there was a guy who tried to improve the sound of the phone's loudspeaker and he kinda managed to do it by editing the file), by changing high-pass filter frequency in every "device"
//BLOCK: (srs_hpf_0) HiPass - Device 0
//=-=-=-=-=-=-=-=-=-=-=-=-
srs_hpf_0:hipass_order = 4 // Filter Order -
srs_hpf_0:hipass_frequency = 60 // Filter Frequency -
srs_hpf_0:hipass_is32bit = 1 // Filter Precision (16bit when 0) -
srs_hpf_0:hipass_skip = 1 // Skips High Pass Filter when true - toggle

but there aren't any results.
I don't really understand the types of devices and that they do (WOWHD, TruEQ, CSHP and so on).
Maybe there is any other cfg files who process audio input, because it's the same high-pass filter when recording on internal mic and with external 3.5mm mic.
Let's try to solve this problem everybody, because, as HTC support said
HTC is not designed for capturing things in loud environments

Yeah, whatever... It can do it!

Don't mess with HPF, REALLY DON'T!
I have been experimenting with SRS trumedia 51 and music, HPF messes up when enabled!
these settings you have posted are from SRS_global which won't really do much, install musicBox and you can get SRS working...
There is a reason why you sould not enable HPF without know what values are right, I tried this and it made a mini explosion noise (a sqeek then a loud POP) when starting audio, I highly recommed you do not mess with it. Anyways, SRS will NOT do anything with audio recording, your best place to find audio recording values are in the media_profiles.xml in /system/etc
SRS has nothing at all to do with recording audio, only to output the SRS effect.
I hope this info helps
WOWHD is SRS WOWHD, this is a sound effect which enables a true surround sound experience.
TruEQ is SRS's native EQ settings, not much to say here...
CSHP is SRS CS Headphone. Or as I would like to call it, Dolby Digital 5.1 (Because it IS the exact same effect) (CSHP is only used in srs_truemedia_51) (HTC Enhancer uses this file)

Thank's for your answer.
I can't understand, how nobody is interested in improving audio recording quality, when it's obvious that it's a software limitation thing.
We have an almost perfect phone with good camera, but we can't fully enjoy watching and LISTENING recorded videos, because some "clever" people in HTC decided that it's normal to high-pass the mic and put a compressor on it, without any gain control - in result we have a tragic audio from loud concerts and even LOUD voice conversations (where people are sceaming a little bit).
Maybe someone has a solution?
Maybe HTC will offer switching to a ****ty iphone, which has almost perfect audio recording quality (for a phone)?!
