I recorded a short clip of my voice with HTC's Voice recorder app. Then i went and downloaded TapeMachine Lite from the market. WOW what a difference. I always thought the DHD's poor audio recording was down to hardware, but clearly not. HTC for some reason set the audio output to 8000Khz, but TapeRecorder records at 44.1Khz or 48Khz, in a format of your choice (WAV is default).
So i was wondering, how easy would it be to implement this quality recording in the camcorder app? If someone does this then i'll happily shell out some money for the cause.
I just repeated what you've just posted. Wow, what a difference. Why this isn't default on the DHD camcorder I don't know.
I think the sample rate in the camcorder is a limitation of the audio codec that is used, just guessing tho as I'm not sure of the all the limitations with aac-lc
Sent from my Desire HD using XDA App
no the camera 720p encoding is AVC h264 with AAC audio, the standard is baseline L3.1 and based on this standard the audio should be encoded at 44khz 160kb bitrate
8khz is just one of those amazingly stupid things HTC keeps on slipping in, i don't know if its done to lower the stress on the recording frame rate
i sent them an enraged email about this a while ago and all they said that its passed on to the accurate department
but with 8khz i was surprised at the loudness of the recording, which explains your post today
can someone fix it with a patch? and while at it, please increase the screen red saturation a little

I know the people here are very talented and I hope someone can help. I had high hopes for the video recording on this phone. When the reviews came out I was very disappointed in both the pic and video quality. Every 8 mega pixel camera phone out there beats it. Even the 1 year old Omnia HD. I can live with the pic quality but the video quality is what really frustrates me. Yea it records in 800x480 but whats the point if its pixelated and washed out. Not to mention the highest frame rate it can go to is 26fps. Ohh and the audio quality is horrendous. When the Omnia HD came out it also suffered from bad audio quality but in a later update they addressed the issue. Most phones coming out now record in AAC audio which the Incredible obviously doesn't. I just wish someone can up the frame rate to 30fps, give the video a higher bitrate, and change the audio to AAC. IF you have spare time can you unlock the 720p recording.
That would be extremely useful over any custom Rom in my opinion.....I'm actually considering returning my EVO based upon those issues alone and i doubt HTC will fix it during the next 15 days or so
nooooooooooooo

please no....! we will miss you soooooooo much... !!!
i couldnt resist...!
Grounding really affecting you at all? The screen works fine on my EVO grounded or not, curious to see some testing on stock and custom roms. audio recording will be improved by someone, whether it be us or htc first idk but it will happen.
Yes I'm having serious issues with my screen and the audio quality when rec hd video sounds like an extremely low bit

mine sounds ok, http://www.flickr.com/photos/mrono/4679553815/in/set-72157624101720673/
The problem with the audio is that it's recorded in 8KHz Narrowband AMR audio codec. Also, the video codec is generic MPEG4 at 6Megabits/sec which is significantly less impressive than H.264 at the same bitrate.
Any ideas why the EVO could not record directly into H.264 video and AAC audio codecs?

I'm betting HTC didn't want to pay royalties to use the H.264 and AAC codecs, as they are both licensed technologies and not open source.
I noticed after coming from recording something with live music: the nexus ones audio recording quality SUCKS! I say this because my friend recorded the same thing with his palm pre, and its much nicer on the ears. I was reading something about the nexus using the inferior amr codec for the audio portion of the video, and was wondering with the new 720p hacks was this overcome...
It's known that the EVO's video recording bitrate is low, but what seems less known is that the audio for the EVO's video's are encoded at 8kHz using (what seems like) the AMR telephony codec. Hence, the audio sounds like crap.
As I know nothing about Android software development, I just wanted to ask if its even possible for a real developer to A) mod the current EVO's video recording app to have better A/V encoding or B) develop a 3rd party camcorder app for the EVO have has better or adjustable quality settings?
for use that have the samsung moment we added things in the build.prop and changed the code there if you guys have the same thing you can try that. im not sure.
I thought that the SGSII could film in stereo given that it has two mics. The video I've shot are all in mono. Any ideas?
it records to mono..but this isn't real problem..
problem is that records fuc..ng 16khz sampling rate!!!!
I hope that some software or coocked rom enabled 44100hz sampling rate recording
If the resulting files are mono, my guess is that if you filmed in HD, the phone should not be limiting the quality in some way. So either the 2nd mic is used for noise filtering in the video in some form, or it's just not used in the same way as the main mic and cannot be used for video recording.
LOL! The irony of being able to record in 1080P full HD, but with mono, 16 KHz sound quality
Agreed. Anyway to improve this using 3rd party app?
maybe you can..I can't try beaucse I haven't still the phone
