Best audio compression

Hi, trying to make a DVD of a music work, but I get a slight hiss when it is transcoded, I've noticed the audio bitrate, thing 192, but there are higher settings, up to 400... if I set the bitrate higher,w ill the audio compress better..thanks, I'm a bit clueless aobut all this...

The DVD Specifications state that Stereo Dolby Digital must be at least 192kbps. You can go up to 448kbps, and expect the disc to play on all players. Going any higher than this will make the disc out of spec if this is the sole stream available.
LPCM is uncompressed. This carries a data rate of 1536kbps, as no data is thrown away by the perceptual process. The downside is that you lose bitrate available for film, but if this is a music title, LPCM is your best bet.
Simply export from Premiere as Uncompressed 16 bit 48KHz.
You may - if you wish - elect to go with 24 bit 48KHz, at a data rate of 2336kbps or similar.

Best volume/compression settings for AUDIO for Rock concert DVD ???

I am putting the finishing touches to a 2 hour rock concert DVD.....
I am converting the wav/and 5.1 to Dolby 5.1 and 2.0 files ....
They are sounding really quiet compared to the original waves...???
I can see that there are some dolalogue/audio compression settings and something set to -21db.....
How can I make them louder...and if I do will it mess up playing on normal DVD's ....
I know there are some DOLBY compresor settings in mac DVD player that make the sound pump if switched on...
Any thoughts or help would be appreciated???

Hi
You must change some settings in the standard Dolby presets to keep the original level and mix:
- Dialog Normalization: -31
- Compression preset: none
This way your AC3 files will keep the level and mix from your original files.
Hope that helps !

What settings give the BEST audio quality (original audio CD to iTunes)

Further to my last post, can ya'll PLEASE help me get the bottom of this? I have heard so many different opinions & need to resolve ASAP....
What pref' settings will give me the VERY BEST audio quality, when importing original audio CD's into iTunes 4?
File size is of no issue (I have TONS of storage). I aim to import all at the highest quality possible (files need to be "broadcast quality" - for playing through a big PA system). I have been advised to either.....
1. Import using the AAC encoder at a stereo bit rate of 320 kbps with a sample rate of 48.000 kHz.
2. Import using AIFF (lossless uncompressed).
3. Import using Apple Lossless (lossless compressed).
WHICH ONE SHOULD I USE? Bearing in mind that the files will be played LOUD through a professional PA system & I'd prefer the crowd not to notice a significant diference between iTune files & orginal audio CD's (I will be spining both, side by side).
Cheers - Sweetamix.

You are finding out that the answer to this question tough. Everyone has their own opinion on this one.
I saved the responses to a topic I opened six months ago on this same subject. I saved them and cut and pasted them into one document. Here were the answers I received. Good luck. bob

RE: Classical Music & Bitrate
My experience with classical music (and music in general) is that the higher the bitrate, the better the quality and richness of the music. On the other hand, there is a limit to how much distinction your ears can make, and I think that anything above 192 kbps (mp3 format) is not significantly better (and not worth the larger file size). And in terms of volume adjustment, I personally have not found any need for it.
RE: Classical Music & Bitrate
I copied the same CD to my computer in 128, 160, 192, and 320 bitrates, and I couldn't tell a difference between any of 'em. I was listening to them with Grado SR60 headphones too.
RE: Classical Music & Bitrate
I’m sure you will get several if not many responses. You may also find they vary with the preference of the individual. However there are some rules of thumb. Generally speaking I think you will indeed find the higher the bit rate brings you closer to the CD sound.
Certainly, 32-bit rate does not offer very good sound quality. Actually going from 32 to 320 should have been noticeably better, if not…. Then you’re in good shape. Because what you don’t know is there, can’t be missed.
Also, the bit rate is only part of the equation. What format codec <http://docs.info.apple.com/article.html?artnum=51910> are your songs ripped to.
Consider the following - iPod: About compatible song formats
<http://docs.info.apple.com/article.html?artnum=61476>
MP3 (from 32 Kbps to 320 Kbps)
MP3 Variable Bit Rate (VBR)
AIFF
WAV
M4A AAC
Apple Lossless Encoder
It sounds to me as though your songs may be in MP3 format. As a suggestion you might try ripping your CD’s to 128 AAC format. The general consensus is that AAC is better than MP3. Give it a shot…for the heck of it, and see what you think.
Finally in the end…..it matters little what we all might think….If you think your sounds are better ripped at a MP3 320 bit rate……Great. If not…experiment, and play around till you find what sounds wonderful to you!
RE: Classical Music & Bitrate
Sorry for taking so long to get back to this thread: had two twelve-hour work days in a row.
I did a Get Info on a typical piece in my iTunes and got this
Kind: AAC Audio File
Bit Rate: 128kb (have some at 192 & 2 or 3 at 320)
Sample Rate: 44.100 kHz
Profile: Low Complexity
Channels: Stereo
Volume: +2.3
I was troubled that one responder couldn't tell the difference among 128, 160, 192, and 320 bitrates even using Grado SR60 headphones!
And another seems to be of a similar opinion when he says that I think that anything above 192 kbps (mp3 format) is not significantly better (and not worth the larger file size). Does this apply to AAC format, too?
However, I am going to continue to add tunes at the 320 bitrate - for a while - because I swear that I can tell a difference when I play them over my car radio via the cassette adapter.

What format is the best audio format to use in iPod touch?

I want to know the difference between MP3, AAC and Apple Loose-less audio formats and I want to know as soon as possible. I knew that AAC and Apple Loose-less formats use more size than MP3. That's fine with me. I just want to listen my songs with the best possible quality. What is the best audio format?

Apple Lossless would give you quality identical to that of the original CD, but the files will be very large. A 3-minute song in Apple Lossless will be around 18 megabytes, versus about 6 megabytes for the same song compressed with AAC at 256 kbps. For an iPod, Apple Lossless is probably not an optimal format, since unless you have very high quality earphones or connect your iPod to a good stereo playback system, you won't really take advantage of the quality of Apple Lossless.
For most people, the optimal tradeoff of quality versus file size is AAC at 256kbps. But as Niel suggestion, import a couple of CDs using different codecs and bit rates and decide for yourself. Quality depends on your playback system and what your ears can hear, so only you can decide what will be optimal for your situation.

[SOLVED] Audio Compression Quality

I would be interested in views about which compression algorithm (MP3, OGG, AAC, etc) gives the best reproduction quality for a given bitrate (e.g 160kB/s).
Thanks in advance.

That one is easy: ogg vorbis is the best audio codec. Some might say opus is better. Well yes it is, but just kinda better. Why do I still prefer and recommend vorbis? Because opus only supports 48kHz. This results in an upsampling of most audio material, which usually comes in 44.1kHz. For lower bitrates (I'd say \leq 128kbps) opus of course beats vorbis, but with 160kbps (or -q 5 in oggenc) I'd say vorbis is the best for music.

Unwanted audio compression

Can anyone help?!!
I'm trying to output a movie to tape but it keeps compressing the audio. Louder passages keep being knocked down. I don't understand why as I have not added an audio compression filter. It's not compressed when I play it in the timeline. Any ideas anyone??
Mac Pro Mac OS X (10.4.9)

and a teensy bit more:
Your problem could have just as much to do with the "soundsticks". I just looked them up. They are small speakers intended to be used as computer speakers. They in no way represent or emulate a studio monitor that one might use to make audio decisions. Even if they sound great... in fact especially if they sound great. If they make "improvements" on your sound, then those are improvements your listeners aren't going to hear.
This should pretty much make the case: "SoundSticks II employs a new computer-optimized multi-band parametric equalization."
So the problems you're having could be originating with the prejudices of those epeakers affecting your audio processing decisions, which in turn affect what comes out the other end.
To have it come out sounding like "compression" is a little odd, but it may just have to do with your relative perception of the sound coming from these different speakers.
The best way to judge audio is in a clean soft neutral environment, with good nearfield monitors.In addition (and not simultaneously) you should be able to hear some representation of how your mix is going to sound on a little 3" speaker in an average TV set. One way to do that is to play it through your TV set.

What is the best audio interface to buy to record drums?

What is the best audio interface to buy to record drums? Looking for something with 8 inputs to mic my drum kit. Don't want to go past $1,000. Been looking at the Presonus Firestudio and M-Audio Profire 2626, for example. This is my first time setting up a home studio so any suggestions would be appreciated!
Thanks.

The MOTU interfaces are a good value, and as Pancenter notes, they have rock-solid drivers. I've had good experiences with the Traveler, although I'd bypass the mic pres if possible.
And if you're able to spend a bit more, the Metric Halo 2882 also has excellent drivers and noticeably-better sound--it's my fave in the <$2k range. If you can find a used Apogee Ensemble, that's another great-sounding interface, although it can't match the latency performance of the MOTU or Metric Halo. So, for software instruments, the Ensemble is not a good choice, but for recording acoustic drums, a used one for $1300-1500 would be excellent.

Best mp4 compression possible for 50" TV

Hi,
I need to compressed my project (24fps, 1080p from FCP) to mp4 which will be run on a 50' TV via a computer (not sure what software but I was told it needs to be in mp4 format). If size isn't a factor, what's the best possible compression to get a very good quality on mp4 format? Should I take the mpeg-4 setting and modify the bit rate to HIGH VBR?
Any help appreciated.

The High VBR should do a decent job. Whether it's the best you can do will require some testing on your end.
There was a recent thread on working from the H.264 presets and simply changing the extension to MP4 after encoding the file. I'm not sure whether that would work or not, but you could try. It certainly would give you comprehensive control over your quality.
Alternatively, you could use MPEG Streamclip, which offers pretty good control but will definitely put your file in an MP4 wrapper.

Best audio connection

Best audio connection ?
a) itunes computer via RCA stereo connection to home theatre
b Itunes computer streamed to Apple TV , Apple TV connected via optical cable to home theater
c) this I have not tried ... Itune computer connected directly via HDMi to home theater
Also does the sound-card in the computer make a difference ?
Antoine

I have Fredereih ataxia so my only hobby left is musique and no way I have the dexterity to insert a cd in a tray, I have 400 cd's all ripped at 196kb.
I love my Ipad with Itunes and the remote app to take control of my 5 computers in the house.
My apple tv is ok but I do not have a good internet connection.
In the room where I listen the most music, I have a small EEE laptop.
it is directly connected on a 925 pioneer receiver with 9 speakers (RCA)
Also in this room I have the apple TV connected via the Digital audio cable
Recently (I'm in Canada ) I have been using RDIO (Like Pandora) , they claim sending in 256 kb.
I now notice that here is a difference in Quality for the same file sent it different ways.
played directly from the Pc is not as good as if I use Airplay ?
a) should I resample my 400 cd's at 320kb ?
b) should I buy another Laptop with a good soundcard and a HDMI output.
I would appreciate any recommandation for any laptop under 1000$ ( Only Itune will be o n it.

Is Logic Pro the Best Audio Recording Software for Mac?

Couple questions. I do a lot of audio production and work currently. I use a gateway with Cubase, and its not bad, but I feel like I need something mroe high end.
I'm looking at the 17 inch Imac. Does anyone record using this computer? How's it sound? Is there any way to put in a new soundcard or something if i don't like the current one?
Secondly, is logic pro the most advanced and best audio recording software for the mac? Are there others as well?
I know about Pro Tools, but it seems like there isn't anything high end enough that is TOO high end.
Does the Pro version have superior mixing capabilties. I am primarily going to be micing a guitar amp and having a mixer run into a firewire port, and also using a preamp for my guitar direct into the computers USB.
Lastly, how are the mixing features on Logic Pro vs. Logic Express? I do a lot of post production mixing as well, and use VST plugins. Speaking of that, will it accomodate using a drum program like BFD through VST or Midi like Cubase will?
Thanks for your time guys.

Yes, you do indeed need sth more high end.

like the current one?
It's not an iMac, but a faithful PowerBook G4 that I am using. Apples Core Audio is awesome. Your sound, however, will depend on your interface.
Secondly, is logic pro the most advanced and best
audio recording software for the mac? Are there
others as well?
That's why we are here, and that's why you ended up in this forum as well
To me personally, Logic sounds warmer and bigger than any ProTools system I've ever heard. From what yopu described as the work you need to do, there is no comparable application. Logic also offers you many more features above and beyond what you currently need to do.
I know about Pro Tools, but it seems like there isn't
anything high end enough that is TOO high end.
Everybody is using PT, and you should maybe get a Light Edition version of it. However, as stated above, Logic offers by far more possibilities.
Does the Pro version have superior mixing
capabilties. I am primarily going to be micing a
guitar amp and having a mixer run into a firewire
port, and also using a preamp for my guitar direct

For your purpose, Logic does have superior mixing capabilities. In my humble opinion, only the popularity of PT made it become the choice of studios and engineers, but things are turning...
Lastly, how are the mixing features on Logic Pro vs.
Logic Express? I do a lot of post production mixing
as well, and use VST plugins. Speaking of that, will
it accomodate using a drum program like BFD through
VST or Midi like Cubase will?
If you do post production mixing, forget about Logic Express altogether and go for Logic Pro. LP will accomodate tons of plug-ins, and it comes with a bunch of great one's as well!
The format for the plug-ins is called A(udio) U(nit) and works flawlessly. Many VST plug-ins are also available in AU format and the development of those is moving fast forward.
In other words, yes, you will be able to use BFD in Logic by means of the AU format.
Thanks for your time guys.
You're welcome.

What's the best audio filter and settings to eliminate echo?

I shot an interview in a hallway. What's the best audio filter and settings to reduce/eliminate echo?

There isn't one. You will be trying to remove the same frequencies as those you want to keep.
Reshoot it, strategically position some heavy drapes and use close miking such as a lav and reliable monitoring quality headphones.

Multi-clip Audio Compression

Is there a way to apply audio compression to multiple clips simultaneously? I had some audio difficulties and was using the camera's compression in early shots and not in later ones, so the balance, levels, and dynamic range are significantly different. The uncompressed sound has much wider dynamic range and clips in a few spots, so I can just pull the levels up.

Select a bunch of clips in the timeline.
Use Modify>Levels.
You use Absolute or Relative to make adjustments.
Relative may be what you are looking for.
