Distorted sound quality in AIR 2.6 on iOS

I am experiencing significant distortion of mp3 audio files (a child speaking) in my iPad app built with AIR 2.6. I have tested the audio files on the device in other apps, and can confirm that the problem is specifically with my app, not a problem with the audio file or the device. This is a critical issue for me and is preventing me from submitting my app.
I am using AS3, not Flex, and I am using a SoundChannel to play the file.  Does AIR software decode mp3s or is it using the hardware?  Are there mp3 compression settings that are better/worse for AIR audio?  I tried a 48kbps Mono file and got a little distortion, so I bumped it up to 96kbps Stereo and got a lot of distortion!
Anybody have experience with this? 
Adrian
PS.  I am completely unable to search by forum on Adobe's site.  I can use the general search, but once I am in Mobile Development there is a separate "Search this Forum" field, and that always turns up 0 results no matter what.  It would sure be great if this could be fixed so that we could find each other's threads better.

I noticed it too. While testing FLVPlayback of a live stream, on iphone 3gs and 4 at the same time, the iphone 4 was giving that weird jittered audio and the same build of the app on 3gs was playing without any problem. I think on iphone 4, when I run a newly installed app for the 1st time, it was doing the weird audio then if I close app and open the problem is gone, or maybe other way. I was using CS5.5 with air 2.6.
The audio was mp3 / 48-64kbps.
I think it went away after I made some changes with GPU settings or the nativeapplication activate state etc, something not related to audio I made change and somehow it is gone. It was using retina display on iphone 4, so I assumeit was a cpu load issue.
I have that app built with cs5 and PFI and there was no audio issue like this.
I hope this helps , and thanks for great work.

  • HF-300 Sound Quality - Loudness and Distortion

    Hi,
    Just wondering if anybody has any comparative testing on the sound quality and loudness with this unit. I am not sure if mine is faulty or just the best that can be expected from the speakerphone.
    Problem is (tested using n95 8 gig and n80) that once the volume is turned up to 70% or more the units sound is distoted terribly. Sounds like the speaker is vibrating and crackling. The symptom is like when you turn up the volume on any speaker beyond its capability which then gets that distortion/vibration effect.
    That said when used below 70% volume its too soft to be useable for everyday driving conversations.
    Golden question if you own the HF-300 also is can you put it on 100% volume and have loud and clear sound without any negative sound quality? May help if you mention what phone model you have tested youyr with also.
    I really think it must be a fault as everything marketed and reviewd about these units states 'loud n clear'. Surely its meant to be used on 100% also without such distortion or why have 100% volume possible.

    Sorry to ask again but is the car kit installed with an additional single Nokia speaker or is all audio played through the car audio system (original car speakers)?
    Most likely in the second case is that the installer has routed the audio incorrectly.
    The kit has two outputs: stereo for music and mono for calls. Mono calls can be installed to run through the single Nokia speaker but musics should be installed to run throught the car stereo 'aux in' channel, hence the question about what audio is distorted.

  • Poor sound quality and distortion

    Ever since getting my 27" Imac I've notice the sound quality is poor and bass sounds distort quite a bit and it happens with the computer's speaker, headphones, and streamed audio over the network.
    Any ideas on what might be causing this? Sound card or itunes?
    Thanks,
    Terry

    Sounds like an audio circuit issue on your logic board--especially if it does it using headphones too. That almost eliminated the speakers. I would contact Apple and get it looked at.

  • Poor sound quality when using air play

    How do I fix poor sound quality when using air play with my Denon receiver?

    I am not too sure if this is affected by BT software stack or RF design...
    iPhone 3G with FW 2.x provides Cisco VPN as well as Email support for corporate usage. However, it's weird that business man wouldn't want to use BT headset and talk to people... We are not asking about new feature support, like A2DP, but reliable, stable BT connection ONLY!!
    I've read that lots folks spent a lot of money on purchasing many different BT headsets and tried to get it work with iPhone 3G. I myself tried: Plantronics 510/815/855, Sony HBH-DS970/980, Nokia BH-903. None of them can work fine with my iPhone 3G ever! And iPhone 3G even cause BH-903 and DS-980 hang up after pairing or finishing call!!
    That's why I don't believe it's just a "SPECIAL CASE". How could a product FOR BUSINESS purpose get this kind of basic function problem?
    I hope we will find this issue could be resolved completely with new F/W, like Safari crash problem before. Other than this BT IOT problem, iPhone 3G is really the phone/companion could provide complete solution fulfill my personal and business needs.

  • Sound quality and coolers  on Macbook Air

    Hello everyone ...I just bought a macbook air (1.86GHz, 128 SSD...) and I'm quite disappointed by its sound quality .... when I pull up the volume it sounds like worn-out speaker. My old macbook white sounds much much better .
    Also it's getting hot and the cooler makes disturbing noise like a desktop machine all the time not only when I run applications. Is this common for all the macbook air(s) or I just need to take him to the doctor ?

    Hi softiam,
    One thing to note on the MacBook Air, is that it has only one speaker. Unlike all the other Apple portables, there is only one speaker (located in the area of the return, shift, question mark, apostrophe keys).
    With mono, versus stereo, sound the quality will sound different but it certainly shouldn't sound washed out. What are you listening to, something through iTunes?
    What are you doing on the machine when the fan ramps up? How are you using the machine, is it on your lap, on a desk? What applications are you running?

  • I play music on my hi fi via an airport express attached to my iMac. Since installing maverick the sound quality is terrible and I get frequent distortion, which never happened before. I have reset the airport express and reconfigure my wireless settings.

    I play music on my hi fi via an airport express attached to my iMac.
    Since installing maverick the sound quality is terrible and I get frequent distortion, which never happened before.
    I have reset the airport express and reconfigure my wireless settings. I have also used Ethernet on its own but still get the same sound problems.
    I would love to turn itunes sound off as you used to be able to do, but this I believe can't be done.
    Has anyone else been having the same types of problem, and better still has anyone got the answer?

    When the AirPort Express Base Station (AX) is connected by Ethernet, you will find an option in the AirPort Utility, labeled: Enable AirTunes over Ethernet on the Music pane. Just select this option to allow streaming iTunes via the AirPort's Ethernet port. You should also be able to disable the AX's wireless so that it shouldn't interfere with the nearby TC.

  • IMac Aluminum Sound Quality Distorted

    I am experiencing distortion (sounds like there is a little bit of overloading) on my new 24" iMac Intel 2.4Ghz through the speakers, with headphones and with external speakers. OS (10.4.10) is up-to-date...Very frustrating seeing that I want to record and mix with this system. Anybody else experiencing this situation???

    Since my last post, I've updated to 10.5.2 and the issue still exists.
    In addition, recently I've been doing some recording in GarageBand and have not noticed the issue while using headphones. This may be due to the fact that I'm usually listening back to the recording for no more than two - three minutes at a time, and usually much shorter intervals than that. Since the issue is sporadic, once every 10-20 minutes or so, I'm not surprised that I haven't run into it there. I'll have to try again listening for an extended period. This issue does not exist at all on my MacBook.
    This issue is getting more annoying every day. The iMac serves as our TV, watching abc.com, hulu.com, etc., so I notice it frequently. Has anyone heard anything from Apple on this? Or reports on other tech sites or blogs?

  • GD580, its sound quality and its specs

    I bought the GD580, and found, to my utmost annoyance: the sound quality is way below my cheapo Panasonic micro system. You know what: I paid USD250 for the GD580 and the same for my micro system.
    At one point, I thought that because the GD580 included a decoder, it would enrich my sound if I toured the sound from my system through it to the Creative speakers, using the optical cable. Plainly wrong. Bad speakers or bad amplifier, or bad decoder, or all of those reasons.
    Believe me, the sound from GD580 is no way as full as the sound from my system:
    - Bass is OK, until you turn up the volume, and it's not bass anymore. I would not call it music.
    - Lower Medium is OK,
    - Higher Medium and Treble are where my little system would give the GD580 a run for its money!!! It's no way as full as I would have expected. Poor me, wrong decision.
    Creative has been well known for its speakers and amplifier, I believed, so I was looking for reasons in the decoder itself. Hey, the website lists virtually no useful info. on the decoder specs. I was wondering if it's the same quality part as used in the stand alone decoder DST-100?
    My little system states: they use a 24 bit / 92kHz DAC (digital to analog converter). The Audigy 4 uses a DAC of the same specs. Does anyone know if the decoder in GD580 uses that kind of part? Or just because the GD580 uses a 6 bit / 44.kHz DAC, sound quality is inferior to an average system?
    What ever the result, I must say: stay away from this GD580. Anyone has any suggestion for a better system? Further info: I use it in an environment no larger than 5 sqm.
    Thanks for reading this lengthy message to its end. But I was frustrated indeed.

  • Distorted sounds in Windows 7 32 bit

    Hi...
    I re-installed my system with (Dutch) Windows 7 32 bit and used the "Vista" driver CD for my SB X-fi Music card.
    When I play MP3 or WAV files, the quality is reasonable, however, some sounds, specially vocals, are damped by the bass-tones.
    When I play a CD in my Plextor 80SA dvd drive, I get a very distorted sound.
    Doesn't matter if it is a burned CD or a original CD from the music store.
    I think that the output from my DVD dri've is to high, but I don't know where I can change the output level.
    Also tried the latest updated drivers for the X-fi card, but that has no change in the sounds, cd's are still distorted and basstones in MP3 and WAV damp the vocals and other instruments.
    Don't know what to do...please, someone with advise?
    Grtz.

    Using earphones, the same thing happens, the bass tones dampen other sounds.
    I tested the speakers with the Creative Diagnostics application and there seems to be nothing wrong with them, even when I pump up the volume to 80 or 90% of the max volume there is no distortion at all in the speaker system.
    I have ripped a CD and played the saved MP3 or WAV?files, they do the same as downloaded MP3 WAV files, bass tones dampen the other sounds. Sometimes the first two or three songs played, are all fine but then it slowly starts to happen... In other occasions, it happens immedaitely.
    I have two identical dvd drives in my system (running on Windows 7 Ultimate) and used the second (hardly used) spare drive, also a Plextor 80SA, to play a legal bought CD and this one gives distorted sounds too! Volume doen't matter, by the way, distortion is also present on low volumes.
    I must add to this that, when I was running Windows XP Professional with SP3 on my system, none of the above happened... It all started after re-installing my system with Windows 7 Ultimate.

  • Why is the sound quality on iPhone 5s videos so poor compared to iPhone4?

    I used to take lots of videos with my iPhone 4 at nightclubs and or music shows and the sound quality was always very good.
    Now I have just bought an iPhone 5s and the last thing I expected was that the sound on videos would be clipped and distorted badly.  Does anyone have any suggestions, or is it simply that the new phone is rubbish compared to the old one (I really hope not)?

    It could have to do with the noise-cancelling microphone on the device. If you are in a loud area such as the shows, it is trying to single out a sound, normally closest to the phone. I'm not exactly sure if this is the case when recording video. I just know you can turn it off in Accessibility, but that mentions phone calls. Worth a test though.

  • Why such sorry sound quality on iTunes? On some of my purchases the sound level is suppressed on the audio. On others the volume is so low that if I have it set for another song and a new one starts I have to increase the volume to hear it.

    Why such sorry sound quality on iTunes? On some of my purchases the sound level is suppressed on the audio. On others the volume is so low that if I have it set for another song and a new one starts I have to increase the volume to hear it.
    There is so much distortion on some of the music I have to play it with QuickTime to get a "clean" track.
    What can be done to get a consistent volume level or is this another typical Apple product that you have to take what you get and be happy because it's not a Microsoft product?

    If that's the best you can do why don't you get on another forum?

  • Improve/extend equalizer and add 3D sound. Sound quality really poor.

    I've been using the 2g nano for a while now and i must say the audio quality is really poor if compared with my 3 year old iRiver (which only has 256mb memory). Lots of people keep saying how great the sound quality is but i believe people saysing that just dont know any better. For those who do hear the difference the only satisfaction is the storage capacity.
    The Equalizer is a big shock. People (even Apple fans) say its best to leave it off for improvement. Why ? because turned on the music gets heavily distorted. People even blame their earbuds. So people go off and buy a €40 earbud just for that extra bit of improvement which the nano should already provide with the nano itself.
    So this is what should be done :
    - improve overall sound quality
    - add custom equalizer
    - add Xtreme 3D sound (= is a really big ++ iRiver users understand)

  • Sound quality

    I'm making a music sampler Flash movie to play in my site.
    Just a simple one with play and stop buttons. My music file is MP3
    which I set to stream. 44kHz, mono, 16 bit, MP3 compression,
    Quality set to Best. I have the mp3 on its own layer in the
    timeline and the 2 buttons on their layer, using basic behaviors
    for play and stop. When I hit return and play it as a FLA it sounds
    great ..... but when I TEST the movie (SWF) and when I Export it
    (SWF) to Dreamweaver page and preview in Safari, the sound quality
    is terrible.... distorted and trebly. I tried wiping the layer and
    doing it over.... didn't help. I checked my settings..... any ideas
    what's wrong?
    Thanks for your help in advance.

    I should add..... using iMac G5, OS X 10.3.9, Flash MX 2004
    and DW MX 2004.

  • IOS 5 Sound Quality and Sound Check issues

    So since upgrading my iPod to iOS 5 the sound quality of my music has deteriorated massively and sound check no longer works as it should.
    Tracks sound crackly and audio volume will remain balanced for a few tracks when sound check is on, then all of a sudden become completely unbalanced and all over the place. My iPod is only just about useable, it's a bit of a disaster that its main feature doesn't work as it should.
    Everything else in my iOS5 works as it should.
    Any help would be greatly appreciated.
    Richard.

    Since I bought iPhone4 and listened my songs with "Ipod app" and external speakears I was amazed how brilliant, sharp, intense, clear, perfect bass, perfect trebble the sound was, there was no distortions or saturations ever... The sound quality was just PERFECT with the equalization OFF!!!  Not remember if I had SoundCheck ON before but now it doesn't make any difference. I installed iOS 5 over 4.3.1 or so and now sound is just more like noise compared to iOS 4,  I have selected all presets or equalizations but ALL are poor, maybe some presets work better with some songs but still they are poor.... Songs did not have clarity!! The volume force was like degraded, now I have to set higher volume to produce same force than before with less volume... iOS 5 max volume (100%) is like iOS 4.2.1 85-90% of volume. Difference is that iOS 5 maximum volume starts slightly to distort or saturate audio quality... before with iOS 4 sound quality was Crystal Clear even with max volume!!! In short SOUND QUALITY is DEGRADED... or perhaps I'm a very critical and nonconformist guy in terms of audio quality... this kind of degradation is quite notorious when one loves music!! or is there some other configuration I'm missing here??
    Totally agree with Richard!!
    At first I thought it was a problem with my phone... I used to believe iOS 5 was engineered for new iPhone 4S hardware and since it is shipped with dual-core processor, I thought my phone was short in resources!!!
    Why max volume is lower in intensity???
    Why equalization with the EQ Off changed?? All my songs were stored on iTunes, they must have same sound quality properties as they were when first ripped..
    I hope Apple enginneers did not sacrifice volume output force in favor of saving some battery, because normally we charge battery when listening music at home with our personal speakers equipment.
    I would like to understand the reasons why the new "Music App" was "changed", and why these changes have to go backwards!! That is sad... because for iPhone or iPod lovers music was always important.
    thanks

  • IPod w/Cassette Adapter-How to Optimize Sound Quality?

    I have I believe a G2 iPod (15 GB), and I play it in my car using a cassette adapter. I've found that to keep the sound from degrading at above average volumes, I have to make some adjustments. One, I have to set the EQ to 'Bass Reducer'. Two, I have to make sure the volume on the iPod is at about 80%. If I go above that, the sound distorts. The lower you go below that, the more hissing you get w/ the playback. I also turn the 'Sound Check' setting on.
    Any other recommendations on how to optimize the sound quality when playing it through your vehicle sound system? Also, I'm thinking about getting a G5 unit (most likely the 4 GB Nano). Anyone have any feedback on whether I can expect better sound quality, in particular in my vehicle with the setup outlined above, by upgrading to the newer unit?

    Various Methods to Connect to a Car Stereo System, or Listen to Your iPod in the Vehicle
    Best:
    Direct connection via the dock connector or headphone jack of your iPod, to the mini-jack input (or AUX RCA input jacks) of your car stereo. Not many low/moderate-end cars have this feature yet, but it is becoming more popular. Some aftermarket auto stereo units may have this feature.
    There are also some after-market, moderate to fairly expensive direct interfaces, that hook into your existing car stereo to provide a high-quality, direct connection. Most will also power/charge the iPod. Pretty slick, but can be pricey ($80-$300). If money is no object, a clean way to go. Not very portable from car to car – if at all.

    Better:
    Connect your iPod to a cassette adaptor and play your tunes through your car's cassette player. Some new cars no longer come with a cassette player, so it may not be an option. It will provide even better audio quality if you can run the audio feed out of the dock connector (see the SendStation link below). Can be portable between cars that have a cassette player and also be used in your home cassette system. $5 to $20 for the adaptors, with large variations in quality (even with the same model).
    Good:
    Attach an FM transmitter to your iPod and play the tunes through an unused FM station. Convenient, but wireless FM transmitter signals are susceptible to static and outside interference, and can vary in strength and quality depending on your location. Some noticeable degradation and distortion, depending on the quality of the transmitter, the sensitivity of your ears and the airwave congestion in your area. Highly portable between cars, and may be used in a home system. FM transmitters that need to be plugged into a DC auto jack may not work in a home environment (without some sort of adaptor). You can pay from $15 to more than $80 for some of these.....but for FM quality audio, how much is too much?
    Marginal:
    Attach an external speaker system to the iPod and play it in the car. Workable, but not too good - unless you spring for a $300+ Bose (or similar) system. But why? Only if your vehicle has no Stereo system, perhaps.
    Brave Techno-Geek:
    This site gives some directions on adapting a car stereo by yourself. Risky, but it has been successfully accomplished by a forum member. Fairly inexpensive....unless you screw it up.
    Whichever you choose, power the iPod through your car’s DC power -- either from a power adapter, or as part of the combined audio adaptor. Have a method to secure the iPod to the dash/console/etc. See the reviews for all the various accessories at the iLounge
    You will also get better audio output if the dock connection plug is used, rather than the headphone jack. See Sendstation for a novel adaptor called a PocketDock. Others types are also available via this site.
    I have read positive and negative reviews of each method, and within methods there are great variations in performance of different manufacture's systems – and peoples’ opinions of their performance. Some cassette adaptors/FM transmitters work poorly, some better.
    FWIW: I have the iTrip Mini & the Newer Technology RoadTrip!+ FM transmitters, a Belkin cassette adaptor (used both with & w/out the PocketDock) and two vehicles with the BlitzSafe direct interface. Using the same song in the same car, I found that the FM transmitters worked, but not as good as the cassette adapter via the headphone jack. Using the PocketDock on the cassette adapter resulted in a significant audio quality improvement. As expected, the Blitzsafe direct connect was exceptionally better than everything else: less tinny, a more warmer/richer sound, and close to true CD quality.
