Voice recorder and all other 3rd party apps record audio like absolute garbage. I am very disappointed. Such an awesome camera and camcorder but it sounds like I am speaking through a damn kazoo. I am dying to know if it's firmware or just cheap hardware, not to sound bitter but the iphone has a SUPER high quality mic being that Incredible just came out I was very surprised at the low quality of the audio recording

Hey, I have a problem with android programing when I try to record and then play the file that was just recored. I can both record and play the sound but the quality stinks. Its not just bad is really hard to listen to and sound abit like its a computer generated voice. I use the andriod SDK-emulator. The code that sets up the recording looks like this;
MediaRecorder recorder = new MediaRecorder();
recorder.setAudioSource(MediaRecorder.AudioSource.MIC);
recorder.setOutputFormat(MediaRecorder.OutputFormat.RAW_AMR);
recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
recorder.setOutputFile(path);
recorder.prepare();
recorder.start();
And the code playing the file later looks like this;
MediaPlayer mp = new MediaPlayer(); mp.reset();
mp.setDataSource(path); mp.prepare(); mp.start();
I don't know what part that makes the audio file sound really bad or if its just the emulator that makes it bad and that it would work on a real phone.
Is there any possibility to make audio recording with higher quality? And how can I read information that User is saying something? In Audio Recording application you can see such indicator (I don't know the right name for it.
View 2 Replies View RelatedToday I hooked up the headphone outputs of my D.I. to my M-Audio Profire 2626 audio interface and sat down to do some semi-serious testing. I tested using 3 seconds of white noise (to test frequency response), a 20-second 20-20k sweep (to test phase coherence), and the Apples in Stereo's "Sunndal Song" (to test the ability to rock). Signal generation and MP3 conversion were done in an old version of Cool Edit Pro, and Incredible recordings and wave comparisons were done in Cubase 5. I was going to take screen caps and make a whole big thing about it, but, as an older and wiser man once said: I went into these tests being completely happy with the performance I'd got from the Incredible so far, and expecting it to pass with flying colors.
Sadly, I was just a little bit disappointed. Firstly, there appear to be major sample clock issues. "Sunndal Song" is 3:30. By the end of which there was a perceptible audio delay of roughly 35 milliseconds (the D.I. was playing back slightly more slowly than the source file). Meow, that may not sound like much, but trust me, it's an eternity. Oddly, I didn't hear any pitch-shifting occurring, and I have a really, really good ear for that kind of thing. So it's not a sample rate issue, just a clock issue. Obviously, no cell phones are going to have word clock sync or s/pdif output (and s/pdif output would have defeated the whole purpose, which was to test the DACs). I had not expected perfect sync from the Incredible;s DACs, but I had expected better results than I got.
Secondly, on every recording that I did, the Incredible appeared to be playing everything phase inverted. I switched cables and inputs on my interface, just in case either of those were faulty. Meow, this is not a huge issue, since it was phase-inverting both stereo channels at the same time. It's end-user transparent, but definitely not as it should be from a technical point of view. But what I was most concerned with was frequency response. The goal for any digital playback device is accuracy you want the music to be reproduced in the most faithful and accurate manner possible (with the highest, one might say, fidelity). In this area, the Incredible's measured results were pretty good. Here's a link to a screenshot (I don't want to risk the dreaded sidescroll and incur the wrath of the forum).

The green lines on the bottom are the Incredible's measured audio output, the red lines on top are the source file. The Incredible does a pretty good job of both matching the subtle inflections of the original test file, and staying flat up to 20k, above which it drops off pretty quickly but that's fine, since a) that's all the frequency response that was advertised, b) no headphones can reproduce frequencies that high and c) no humans can hear them anyway. Which is why I'm at a loss to explain the very real difference in what the human ear hears from the Incredible when playing a song. I A/B'ed "Sunndal Song" repeatedly, and there are some very real and discernible differences between the Incredible's recorded playback and the source file. I used this song specifically because it's one that I had ripped from CD myself, so I know the files on the incredible and on my computer are identical. The low frequencies (bass to most of you), while it was certainly there, sounded almost compressed. Nothing was gone, but it certainly didn't seem to have the dynamic range (or "punch") that the source MP3 did. At some point, I may revisit this and do specific testing to see if there's any kind of bass compression algorithm built in to the D.I.
It would make sense for HTC to do this because loud, low frequencies with high fidelity would draw a significant amount of power from the battery. The midrange, while it didn't seem to be compressed, was definitely more pronounced and noticeable. The easiest explanation for this would be that HTC built in a mid-boost, but the white noise tests show this to be false. The high frequencies seemed to show the greatest fidelity, without any noticeable compression or attenuation, though the seemingly more pronounced mids tended to distract from them. The good news is that neither my ears nor the Profire saw anything even approaching clipping. The D.I.s audio output was actually very low, but it's designed to drive a pair of headphones, not function as a +4 dBu pro audio device. So I guess my subjective verdict is that, while the Incredible's DACs didn't perform as well as I'd hoped, it's nothing I am going to lose sleep over. It's still fine for riding my bike, plugging into the speakers at work to listen to Pandora, and everything I intended to use it for. Will it ever integrate into my live rig as a sample player? Probably not.
Wondering is there is a fix yet for the poor audio quality through pandora? Sounded much better before 2.2. The only "fix" I have seen drastically slows down performance.
Yes, I did turn on the higher quality sound in the Pandora settings.
Have you ever tryied to make a video when you're at a concert? (I'm not speaking about a classical concert!)
I did and the result was horrible for the sound part. Is there a trick when I want a good quality audio? just keeping the Phone in the air is not enough
Is it possible to change the video resolution when recording on 4.4? I'm using a Moto X if that matters. I'd like to email a video but no matter how I trim the file its too large.
View 12 Replies View RelatedI did not see any other open threads on this; there is a very simple system edit you can perform to record video @ 8 mbps, up from the default 3 mbps. This is from a reliable source. Works very well. Root access is required and, of course, be sure to backup everything before you try anything.
The Droid compresses recorded videos (which results in blurriness and some blocking), so today I started poking around the system files and found this line in build.prop:
Code:
ro.media.enc.hprof.vid.bps=3000000
Which basically means video is compressed at a fixed rate of 3Mbps. I didn't think it would work, but I went ahead and changed the value to 8Mbps:
Code:
ro.media.enc.hprof.vid.bps=8000000
Rebooted and shot a test video. Lo and behold, the video is now recorded at 8mbps, resulting in a MUCH crisper image!
To apply the fix, you need root access. Simply edit that line in your /system/build.prop file. You can pull the file from adb, edit it, and push it back, or mount the /system partition as read-write and edit the file with Astro.
Edit: For the more adventurous users, here's another tip: I've been tinkering with the rest of the video settings in build.prop and comparing the resulting videos. So far, the best setting I have found is actually using MPEG-4 SP instead of H.264, 8 Mbps bitrate, and 30 frames per second. The phone chokes at 30 fps in H.264 mode, but does a pretty good job with MPEG-4 SP, and at that bitrate, the image quality is still very good regardless of the codec. The pertinent settings are "ro.media.enc.hprof.codec.vid" for the codec ("h264" for H.264 and "m4v" for MPEG-4 SP) and "ro.media.enc.hprof.vid.fps" (you can choose anything from 1 to 30)
One known limitation of SDK 1.1 was that audio can be recorded only to a File and not to a network stream. Is this still an issue with 1.5 SDK?
View 4 Replies View RelatedI'd like to create an audio recording in Android. (Actually, I just want access to the mic without recording it, but it seems that's not supported so I'll have to create a recording and tail the file). I'm having a very hard time getting started. Mostly I'm just hoping that someone from Google reads this and will update the documentation because the example won't compile - it looks like it's from some previous version of the SDK because there's an error in every other line. I made my best guess as to what the usage should be, but I keep getting a number of different exceptions. One question I had is whether I can just specify an arbitrary path to the MediaRecorder to start recording or whether I have to create an entry in the content database. The JavaDoc for MediaRecorder.setOutputFile isn't clear on what it's expecting.

View 5 Replies View RelatedI have a Java application where in I am trying to read Audio samples from the mic into a buffer and then write the samples back to speaker from a buffer for playing. I have used AudioRecord and AudioTrack interfaces. Below are my configurations for the Record and Track object creation. AudioTrack(0, 8000, 2, 2, playBufSize, 1); AudioRecord(1, 8000, 2, 2, recBufSize); Using AudioRecord interface I am able to read the samples from mic continiously (8000 sampling rate and 640 samples per read). In the similar way I am also able to write some pcm samples to the speaker from a buffer and play it continuously using the AudioTrack interface (without record). But when I try to do both record and play simultaneously I am able to only record audio from mic but I am not able to play any samples to speaker.

Im trying to record audio directly from the system. Using the standard API, you can only record from the MIC or phonecalls, ala: MediaRecorder.Some ways I've tried is to read from /dev/audio and /dev/eac from my app, but I think the sandbox of the app is preventing this.Im thinking about using the NDK, but Im not sure if that would overcome the sandbox aspect ? Ideally, there is some solution outthere to access the audio sub- system directly. Whether it be directly to alsa, to the AudioFlinger, to /dev/eac

View 12 Replies View RelatedI'm coming from an iPhone 3G, and I have Shure SE115 earbuds. I don't find the audio quality of the Evo to be anywhere near the quality of my iPhone. I don't find the audio quality of my iPhone to be as good as my gf's zune hd. If I put the same song on both my iPhone and Evo, it is immediately apparent to me which one is which. The Evo doesn't go as loud, and it just sounds a lot more flat, and way less crisp. We're talking night and day here, at least IMO.
I don't consider myself an audiophile by any means, but this feels like a huge downgrade to me. I've tried using both the stock music player as well as Doubletwist. It's so sounding. I think I'm probably going to return it, and go with a new iPhone. Anyone else generally unimpressed by the audio quality of the Evo? I'd imagine my beef is with the hardware, and it's pretty unlikely that a 2.2 root would fix my problems.
One of the only disappointments I had with my EVO was that the audio quality through the headphone jack seemed muffled and quiet compared to my old iPhone. This wasn't a huge issue but very noticeable when listening to music in my car through the AUX input. After doing the following, I'm happy to say that the quality now even surpasses the iPhone.
Installed the paid version of MixZing - the price was kinda steep but well worth it since it comes with an EQ. Boosting the overall gain tweaking the low frequencies has done wonders - best music app IMO hands down!
(Following Requires Root and NAND):
Flashed a custom 2.2 ROM - the newer ROMs are using modified versions of HTC's source kernel to boost the audio volume. I prefer BakedSnack 1.4 using his included kernel. Better audio quality and better battery life to boot. Flashed the workaround (or manually edit build.prop) to temporary disable stagefright. This fixes the audio issues with Pandora running on 2.2.
