Not really. MP3 works by throwing away bits of the audio it assumes you won't miss (this gets less and less true as you reduce the bitrate). Once that's done the quality is fixed - you can convert it to AIFF, upsample it, anything you like, but you can't put back what was taken out.
However it's always advisable to use as good an output path as you can. Though they are much improved on older models, Macs' analogue outputs inevitably have a certain amount of mucky noise; any digital output is to be preferred, and a high quality DAC will be able to produce lower jitter (errors in the timing of the sampling rate). However all this is in the interest of making the existing recording no worse: you can't ever actually make it better. (There are digital noise reduction techniques, applicable to hiss and to impulsive noise, but these are a conjuring trick: they always degrade the original signal, but the skill is in using them so that the trade-off in noise reduction makes it worth while. You can't remove distortion or the artefacting caused by over-compression.)

  • When playing videos, connects me to the airplay option of IPad or AirPort.  Can I hook up speakers to my Airport extreme to get a sharable/higher quality sound.

    Is there some kind of USB hook up for speakers that can run off the airport extreme?  This will allow me to watch movies on my iPad with better sound. 

    I guess you could go with a USB audio connection on the extreme,
    As the Jolly Giant points out, audio is not supported on the AirPort Extreme. There is no audio jack and the USB port will only support a compatible printer or hard drive. USB speakers are not supported.

  • Audio - recording high quality stereo sound with iPhone 3Gs

    There are a number of excellent sound recording apps now available for iPhone - notably RecTools 08 (8 track, PCM) but no way to get stereo sound into the device. To date both Belkin and Griffin state their stereo microphones (designed for iPod) will not work with iPhone because Apple has not enabled audio input via the dock connector.
    to the community:
    • Has anyone found a method of getting high quality stereo sound INTO the iPhone?
    to Apple engineers:
    • Is the dock connector software upgradable?
    • Does Apple have any plans to correct this serious omission in it's flagship mobile device?

  • For good quality sound in iPod.

    Hello:
    I'd like to know which way is better to keep a good quality on the iPod. Many people goes for the mp3, OK, compatible with a lot of devices in the world, a lot of songs in a CD or card, easy way, but WHAT ABOUT THE QUALITY???
    AAC at 128 is good, I know. For many users better than an mp3 file at 160.
    I ask what is better or doesn't matter:
    1. All my library (My Music) are in mp3 at 192 vbr. All of them are imported from original CDs. Even so, these songs aound with distorsions, maybe because of the compression. In the laptop and in the iPod.
    This distorsion sounds like a wave, as if somebody is playing with any equalizer button moving from left to right
    2. If an mp3 file (encoded and imported from an original CD of music) is converted to WAV or Apple lost less, will improve the quality? I mean, I wonder if a compressed file (mp3) could "go back" to an "uncompressed" statement? Or is better to import and encode again from the original CDs to a WAV or Apple lost less formats?
    I make the comparison with the video formats. If a DVD is copied to a VHS, the VHS tape will get excellent quality, but if the VHS content is coppied to a DVD, "this DVD will continue being VHS"...
    In my discman, the songs sound excellent (compilated CDs) and sometimes I think that the iPod is so sensitive, so good that captures "and enhance" the audio noises or deffects from the CDs.
    Thks 4 your help.

    mariocarnival,
    Your VHS-DVD analogy is accurate. Once your music has been encoded in a "lossy" format (mp3 or aac) you're not going to be able to get any fidelity back by converting those files to a higher quality.
    For some other thoughts, have a look at Jeff Bryan's post .
    If any of your questions remain unanswered, post back.

  • IPhone 1.0 higher quality than 2.0?

    From the way it sounds, the yellow tinted screen and the plastic case make me think the 1.0 has higher quality parts. Anyone care to comment?

    First off, I totally sympathize with your problem. However 20% is implausible and unless you've asked every iPhone owner, you have no way of knowing how many people this affects.
    That said, this is a support forum, and it seems that a lot of people have tried to offer you....support. If you're unwilling to try what they suggest, then I don't know what you expect. Don't complain about something if you're unwilling to try to find a solution. Please don't think I'm suggesting fault, but it's quite possibly a configuation problem, and you might want to take the phone to a store and let them work on it with you.
    Apple does not do anything offically through these boards, so you *will not* get an answer from Apple here. All you will get are Apple experts, an maybe an employee or two (working unoffically of course) trying to help you. It's up to you if you want to accept it or not.
    Good luck

  • What Is The Best Way To Connect Ipod To Stereo Reciever With High Quality?

    I recently purchased an 80 gig and am a newbie. I ripped all my music at around 280kbps to retain good audio quality when playing in my car and home theatre system. There are tons of accesories out there (docks, jacks, etc) which is the highest quality to connect my Yamaha receiver. I would think a connection to the bottom of my ipod would be of a higher quality rather than using the headphone jack. Any suggestions would be great. I was thinking about using the monster itv link but mostly for audio. thanks

    OK - So now that you have all completely ignored the original question - in hopes of proving your manly-hood....
    Does anyone have an answer to the original question....
    "What is the best way to connect to a high end home stereo to retain the best sound?"
    For sure any connection going through the headphone jack will be a big step back - enough so that you would easily hear a sound quality loss in doing so.
    For the few of you who would like to argue/bicker/rant on the nominal sound quality loss....keep on doing so, but for those who actually have some respectable advice we would love to hear it.
    For the record, I tend to hear just outside the normal human auditory range...
    To help myself put it to rest already... a few years back I decided to conduct my own little listening test.
    I took 6 different common ripping modalities (from lossless - to - 128kbps in both MP3 & AAC.... then transfered all of them in order to a blank. Used the same song for each - the song chosen opened with a few clean crisp bars of high freq. music, followed by an instant explosion/drop into a tight & low bassline.
    The final cutoff that was achieved before I was unable to detect an audible difference was 198 VBR AAC. Having convinced myself that there was the ever sooooooo slight difference b/t 198 & 256, I went with my current ripping status of 256.... Just incase my audible range should become finally honed with age (yeah, like that is really going to happen) !
    This test was run over a Yamaha DSP receiver, running at a constant 110w per channel (w/a max of 220w). The speaker setup was a full surround set of Klipsch Reference Series..... each speaker housing 2 x 6.5 woofer (each housing 2 x 1" Titanium tweeters) And sitting along side the 5 surrounds was/is a 150w continuous 12in. Subwoofer.
    Now I am hardly stating that I have hearing as good as some of you extremely technically profound music enthusiasts out there, but for the majority of people making comments about sound quality, and lack there of - when played over a $120/40w Audiovox radio.... I'm sorry, but I would have to side on that of......"Hogwash, that you can hear a difference!"
    So.... if possible would someone please offer some advice on a dock or cable connection that will allow us to enjoy the music we ripped at whatever
    so-called range we did!
    For those interested in seeing who could hit the further bullseye with their eyes closed, You win!!! Now can you help us?

  • When burning cd makes a high pitch sound

    When burning a cd or dvd  it starts to make a high pitched winning sound

    Hello sirelosealot
    It is nice to hear your opinion but I think it is not so objective. I have the same notebook model since 8 months and my AC adapter does not produce high pitched sound. It runs as expected. For me it sounds like defective AC adapter and I hope you will get one for free (warranty).
    If Toshiba sell thousands of Satellite A210 can you imagine they do such mistake? I do not believe this? Every company has quality control and such mistakes are extremely rare and maybe it can happen by individual products.
    I really do not understand that ASP can say something like this. Strange people!

  • OSS makes very high-pitched sound when turned on

    I recently replaced ALSA with OSSv4 on my Arch install. The sound quality is much clearer, but when I start OSS it makes an extremely loud high-pitched sound.
    I have determined that the sound is coming from input-mix, and I have temporarily solved the problem by checking "input-mix-mute" in ossxmix, but sometimes the mixer settings do not get applied when I boot, and I am forced to shut down my laptop to stop the sound. Do you have any idea why input-mix would be outputting this noise? I would really like to get rid of this problem.

    Quick update - I brought my iMac to an Apple Store, and they identified the logic board as a probable culprit, suggesting a complete swap of the logic board for a cost of >1000 chf (700 USD) - so for now, I haven't fixed it but bought a electrical socket that I can turn off, which (sort of) fixes the problem.
    Unfortunately 2 weeks later the screen decided to give up working, flickering and then pitch-black. Numerous phone calls and store visits later the ony option I'm given is again to replace the logic board. As the unit is over 2 years old and I did not purchase AppleCare, that leaves me between an expensive fit or buying a new one...

  • VHS TO FCP TO QT NOW NEED AVI HIGH QUALITY

    We have a two minute segment given to use in vhs format (poor quality) to begin with. I imported into FCP 4 and exported high qual quicktime and it plays & looks okay on both mac and pc. However, we need to insert video into powerpoint on pc. I'm having a hard time getting anything that is not pixelated and grainy. I've tried the codecs known to work on pc, cinepak & sorenson, same pitiful result. Any thoughts and/or suggestions for 3rd party products? Ideally, getting a higher quality source would be preferable but that is not an option.

    For maximum compatibility MPEG1 is a good choice. Virtually anything in the world can play it. Later machines will also be able to play MPEG2 which will have better quality, but you may have trouble with sound if there is any. Beware of anything with high bit rates, particularly if it is playing back in a window on a laptop. Some will fall over, others will just freeze the laptop screen if you have an external display (projector) connected.
    It will always be a compromise between quality and something that will play back on a system not designed for video (you paid a lot of money for your MAC didn't you.

  • High quality output

    Hello Logic forum members,
    I'm not an expert in sound editing nor in music creation, but I do have a question to ask to this forum that only you can answer in my opinion. Hope this is not inappropriate in this forum. My problem is this:
    I like listening to classical music. I owned a good quality HiFi music system (Musical Fidelity Xcan v3, Sennheiser 650, Denon CD-player 1550-AR for those who are interested). A couple of weeks ago the Denon gave up on me and I am now faced with the decision of either buying a new CD-player... or listen to the music through iTunes and my G5. As I work 90% of my time, this makes a lot of sense to me.
    The only thing is that I don't know how to connect the Xcan v3 to the G5 except through the analog mini-jack of the G5. I can't imagine this will give me the best sound quality. And so I turn to you, music and sound experts in the hopes that you will be willing and able to give me some advice.
    Can the G5 be used as a high-quality music output system? Can I keep using the Xcan v3? Should I buy a DAC and if so, which do you recommend? Is a connection through the optical output better, or not necessarily so?
    Or should I just buy another CD-player (I have my eyes set on a Marantz SA7001 KI, but that one costs 900 Euros and I also would like to buy a new Mac Pro ASAP .
    Anyway, any advice is welcome.

    M-audio audiophile is a starting point but you would need to do some research. hopefully someone else will have some suggestions.

  • Quality sound cards with good linux support

    Since my Auzentech XFI forte is doomed on linux according to most of the internet (if you have one and made it work then please  PLEASE tell me how ) I'm gonna need a new one. Onboard sound just doesn't cut it anymore for me.
    What I'm looking for is a good quality sound card that works perfectly on linux and isn't too expensive.
    I don't care about 5.1 or 7.1, I mostly use headphones so high quality stereo output is of most importance.
    Are there any sound card manufacturers that have some love for linux?
    How are the Asus Xonar cards. I've read good reviews about them but I know nothing about how they work on linux.

    I had an M-Audio Delta 1010lt once that had studio quality sound, linux support is good on the entire delta series.

  • I need a high quality print of a web page..

    Hi all,
    I'm sorry if this isn't the appropriate forum for this but I'm betting you all will be the best brain trust to ask!
    A website has done a feature article on our company and I would LOVE to print out a copy of this page.
    Using the standard browser print options makes the page a total mess.. I've downloaded the "Awesome Screenshot" plug in for chrome and got a decent print of it but it's still not ultra high quality. I'm hoping to be able to print this and frame it... Does anyone have any ideas or suggestions for me?
    Again I apologize for this not being specific to PS (although I do have the entire Adobe suite and may be able to utilize it for this project)... and thank you in advance for any help you may give me.
    Thanks!

    Sounds like you are half way there.  Load that pdf into Photoshop at your required resolution, and rebuild the borders and colours on underlying layers using Photoshop.  The text will be bitmap, but if you load it at a really good resolution, it should look OK.  Or you can overwrite the text in Photoshop as well.  If you load the PDF with Acrobat or similar, you will probably be able to cut and paste the text from the PDF into Photoshop.
    I think you said you have the full Creative Suite?  I'd 'probably' do it with InDesign, but that's a guess without seeing it.

    Hi apple. in the Keynotes about the new iphone you say..

    please i need a new respont.. and check the security about iphone Someone call reply the text messenger from the Block area.

    It sounds as if you only had one line with an upgrade available. So you can only upgrade one line. For you to upgrade as well, you will have to wait until your upgrade is available. You can check that at MyVerizon. That's just how it works. All carriers and phone brands are the same. I have to wait until February to upgrade. The only thing you can do to get the new iPhone, is add a new line. But then you're paying for a line you don't need.

  • How can I upload my FCP project in high quality on youtube?

    Ok so I finished a 4 minute project on Final Cut Pro and it's perfect. But when I bring it out of FCP the quality fails completely. The video is blurry. Even the music sounds terrible. This happens when I export through share masterfile even though it's 4 GB
    I'm trying to put it on youtube. What's the best way of doing it?

    Don't share directly to YouTube. YouTube has bandwidth limit requirements and I'm pretty sure FCPX is trying to upload its usual high quality H.264 video. If you upload a video to YT at a higher quality than they allow, they will re-encode the video for you to fit their requirements. Their encoders are not as good as the ones you have available on your mac... and... they don't care.  The only exception is for creators with enterprise quality internet connections, in which case, youtube will take what FCPX feeds it.
    Use Compressor, or Quicktime 7 Pro to transcode your "master" export out of FCPX (I'll usually just use ProRes 422 LT).
    You need to encode the video with H.264. (Using QT7Pro:) if the video is 1080, then you need to set the Data Rate to 8 Mbps (Restrict to 8000 Kbps); Keyframes Automatic; Frame Reordering off; Optimized for Streaming; Best Quality (Multi-pass Encoding).  Audio: format AAC; Rate 48kHz; (I use) Variable Bit Rate encoding with a sampling rate of 192kbps (typically - anything from 128 to 384). The last step you have to set up: Prepare for Internet Streaming: Fast Start.  As a matter of habit (since this step seemed to make a difference a couple of years ago) I'll go into the Size options and check the Preserve Aspect Ratio by using: option and select Letterbox from the options. [I prefer using QT7Pro because there are less things to screw up. I've never had *satisfactory* success with Compressor — I'm always getting into things that complicate the procedure.]
    Anyway, if you get the numbers under the limit, the upload to youtube is faster, it's "ready" right away (almost as soon as it's uploaded) and you'll get at least what you expect to get (what you see before uploading.) Compressing some types of video (usually high contrast/high action) down to 8Mbps is going to cause problems you'll just have to live with.
    YouTube has an encoding requirements guide here:
    https://support.google.com/youtube/answer/1722171?hl=en
    but it's for PC people... you do not need the .mp4 container, .mov is just fine (been using it for years).
