Determining bit and sample rate of audio file.

Bit of a newbie, and i'm wondering how to determine what the sample rate and bit rate that an audio file has been previously recorded. I'm using Mbox 2 Pro.
Thanks

Open the Audio window and import the file.
cheers

Sample rate of audio files

I need to view the sample rate of audio files in the info menu on OS X Lion. It appears on Mountain Lion but is there a way to get it to appear on Lion?

Drag the file onto the QuickTime icon in the Dock and hit command-i:

TS1717 when trying to import cd the following message appears "the current encoder settings for bit rate and sample rate are not valid for this file"?

Trying to import cd when this message appears "the current encoder settings for bit rate and sample rate are not valid for this file". Any suggestions?

Thanks so very much. I chose MP3 and Download and it is working beautifully. Have a wonderful day and it is so nice of you to get right back to me. I'm trying to cut a DVD for my grandson's grad party and I got most of the photos and didn't have any music since I lost everything in a clean install. Could hug you!

"current encoder settings for bit rate and sample rate are invalid" message

I have some files I am working with. Details and what happened:
Had some music files where I was doing some trimming/splitting. Files worked fine in itunes.
Open the files in Quicktime Pro 7 to trim them. Exported to aif.
Opened the files with itunes. They open and play just fine.
In Itunes I click"create AAC version" to convert them.
I receive the message "An error occurred while trying to import the file. The current encoder settings for bit rate and sample rate are not valid for this file."
I don't know what to do from here. Suggestions?
Thanks.

Make sure that the AIFFs that you export are set for 16 bit PCM.
Also, assuming that you are using 44.1 kHZ sampling in your AIFFs, make sure that you are not trying to use 48 kHz in the AAC.

Having trouble with wav files and sample rates

Hi ,I am having trouble with wav files and sample rates .I have been sent multiple projects on wav as the main instrumental ; I wish to record in 48.000kHz .Now comes the problem.When I try to change the project to 48k It seems to pitch up the track.I can't have them send the logic/project file as most have outboard synths,different plug ins etc.This particular case the producer has recorded the synth task in 41.000 kHz .My successful outcome would be to be able t create a project file in 48 kHz .And NOT pitch up whne I add the instrumenta wav file .Any help would be gratefully recieved,this is my first post so any mistakes I may have made go easy

You'll have to convert the actual synth audio file file that the producer gave you to 48kHz. You can do this in the audio Bin in Logic.

The selected combination of bit rate and sample rate is not allowed.

I've always burned my purchased CDs into iTunes using a AAC 320 kbps and 48.000kHz. Now when I select that option in iTunes 9 I'm getting a "The selected combination of bit rate and sample rate is not allowed." pop up screen. So is it impossible to burn my albums in a 320kbps/48.000 AAC format?. I had no problems in previous versions of iTunes using this setting. I guess I might have to switch over using a MP3 import setting instead.

Audio CDs are encoded with a sample rate of 44.1 kHz. Ripping them at 48 kHz requires resampling and does not improve the quality. Unless you have a special need for 48, use 44.1.

Tony, Make sure you are in Songs view. Then View > Show View Options, and check the boxes for "Bit Rate" and "Sample Rate." See picture:

Creative Audigy 2 NX Bit Depth / Sample Rate Prob

This is my first post to this form
Down to business: I recently purchased a Creative Audigy 2 NX sound card. I am using it on my laptop (an HP Pavilion zd 7000, which has plenty of power to support the card.) I installed it according to the instructions on the manual, but I have been having some problems with it. I can't seem to set the bit depth and sample rate settings to their proper values.
The maximum bit depth available from the drop down menu in "Device Control" -> "PCI/USB" tab is 6 bits and the maximum sample rate is 48kHz. I have tried repairing and reinstalling the drivers several times, but it still wont work. The card is connected to my laptop via USB 2.0.
I looked around in the forms and found out that at least one other person has had the same problem but no solution was posted. If anyone knows of a way to resolve this issue I would appreciate the input!
Here are my system specs:
HP Pavilion zd 7000
Intel Pentium 4 3.06 GHz
GB Ram
Windows XP Prof. SP 2
Thnx.

Well, I am new to high-end sound cards, and I may be misinterpreting the terminology, but the sound card is supposed to be a 24bit/96kHz card.
I am under the impression that one should be able to set the output quality of the card to 24bits of depth and a 96kHz sample rate, despite the speaker setting that one may be using, to decode good quality audio streams (say an audio cd or the dolby digital audio of a dvd movie.) I can currently achieve this only on 2. speaker systems (or when i set the speaker setting of the card to 2.) Otherwise the maximum bit depth/sample rate I can set the card output to is a sample rate of 48kHz and a bit depth of 6bits.
Am I mistaken in thinking that if I am playing a good quality audio stream I should be able to raise the output quality of the card to that which it is advertised and claims to have?
Thnx

Bit Depth & Sample Rate: 24 bit 96kHz? 192kHz?

I am using the Apogee Duet for Mac and iOS on my Mac and I love it - I'm thinking about getting an iPad for mobile recording (voice overs, mostly) and I wonder if Garage Band can manage 24 bit audio at 96 kHz or 192 kHz? I know that the Auria app can, so if nothing else I can just buy that, but since all I would use the iPad for is Voice Overs to edit later in a computer, a $50 app feels like overkill. Comments? Thoughts? Specs?

EMU 0404 USB - DS driver and sample rate autoswitchng

It looks like autoswitching works well until output is going through the ASIO driver. With output switched to DS the "sample rate" option in control panel becomes grey and do not change its value to reflect source sample rate.
Assume nothing is playing via e-mu then I can switch Fs manually in audio control panel to say 96 kHz. Then I start playing some 44.1 wav via foobar + DS out. "sample rate" in audio control panel doesn't reflect 44.1 and remains greyed with Fs = 96.
Is it feature or bug?
What is going out from SPDIF in such case: bit perfect 44.1 or 96 with SRC?

Hmm... there are plenty of possible reasons for this ...here are couple of them (not mentioned in your list of suggestions given by Creative support)
- multicore support could be one culprit (I don't know if the FL has this option but if you use (IIRC) Cubase 3-> )
- on Cubase, another possible culprit is an option named as Lower latency ... disable this feature
- some background process starts after some period (E-MU USB is quite sensitive for these) ... run the DPC Latency Checker utility (just google the name to get it downloaded)
Does Coscos Reaper (google the name) give same issue?

In the past when I have imported my dslr video/audio files and then my zoom audio files Final Cut Pro has organized them in pairs in my library. For some reason my video/audio and my audio are being organized seperately. How do I fix this? Thanks!

Thank you Russ! Seems as though the timestamp on my audio files was completely incorrect so it placed the files far away from the corresponding video. I've modified the timestamp information and this has helped. The hour/minute information is incorrect but at least now I'm in the ballpark. Thank you!

I'm using iweb 3.4 and trying to load audio files to my web page. everything looks good in iweb but after publishing instead of having a control bar i have a "?". does anyone know what to do?

I'm using iweb 3.4 and trying to load audio files to my web page. Everything looks good in iweb but after publishing instead of having a control bar i have a "?". Does anyone know what to do?

Where are you hosting the site, how are you uploading the files and what's the URL of your site so we can examine it first hand?
Adding audio files by dragging onto the web page forces the viewer to have Quicktime installed on their computer in order to be able to listen to them. Look at the audio player options on this page of Roddy's iWeb for Musicians site: Audio Players for your Music Website.

Is there some way I can insert and play these additional audio files, accessible via separate button

I am converting a CD-ROM course to an online format with that software.
In the majority of slides created I have used the Import Audio function to insert a primary audio file containing important curriculum information.
This file typically activates the moment you open the slide.
So far so good.
However, in many slides I also need to insert some secondary audio files.
While the Import Audio function permits me to splice several files into one, this isn't what I want.
Instead, I need to insert one or more additional audio files that can be activated independently via separate buttons on a given slide.
I can in fact do this with the Insert Button function, but in the process a Windows Media Player file opens when I convert the project into HTML.
My question:
Is there some way I can insert and play these additional audio files, accessible via separate buttons, without creating and opening a Windows Media Player file?
Thanks

It is hard to assess the situation without sitting at your computer and having a look myself. First, if you're seeing space savings I doubt all your files are a compressed format. Frequently if you try compressing a compressed format file such as AAC (don't confuse with AIFF) you will actually find the file gets larger because there is overhead to compression and if it cannot compress any more then you end up just adding overhead on top of no savings. Second, normally if you zip the iTunes library it would basically make it inaccessible to iTunes and iTunes would make you a brand new library or at least flag all your tracks as missing (as you are seeing ain part).
I don't know what computer you are running, which operating system, which version of iTunes. Unless they have done something radical in Lion in terms of letting you zip your iTunes folder and still have it functional, you either didn't zip the whole thing, or... I don't know. One scenario is that somehow your media have been split up and you have them in several locations. One isn't really part of your library except for 80 tracks, so when you compressed it (and I still am puzzled by the compression unless it was AIFF files you were no longer using), it didn't really make much difference to the playability. Then you have an untouched library elsewhere.
Use the Reveal In Finder command to see where some of those problem files are located vs. where the playable files are located.

Changing audio recording depth and sample rate in QuickTime Pro?

Last week, I set up QuickTime Pro 7.4.5 to record audio in 24-bit, 48 KHz format -- only now, I can't remember how I did that. I think that I may have used some other software to change the settings of my Mac Pro's built-in sound card. Does anyone know how to do this?
I made several such recordings, just last week, as a test, simply using a microphone plugged directly into my Mac Pro, and using QuickTime Pro as the recording application. During playback of such QuickTime audio files, I can hit <command-i> to see that the recordings are indeed 24-bit, 48 KHz. But now, when I repeat the same process, my QuickTime audio recordings are made with 16-bit resolution, at 44.1 KHz. I remember putting the settings back to those values after my recording session of last week. But I can't remember how I adjusted those settings. Does anyone know how to do that?
Thanks.

Thanks for your response.
I will use Apple MIDI Setup, as you suggest.
I want to change the sample rate to 48 KHz, as the final destination is DVD and I don't want to convert from 44.1 to 48 and thus suffer a possible loss in quality.
As for bit depth, I want to sample at 24-bit, since I'll be processing the sound afterwards and don't want audible rounding errors during the number "crunching". Afterwards, I'll just drop the eight least significant bits, or perhaps round them up or down (to zero or 256).

Core audio and sample rate conversion

I would like to know how to take manual control over core audio regarding sample rate destruct... er conversion. First - I know the workarounds - simply closing the audio player of choice, resetting the external hardware and relaunching the audio player of choice.
setup:
I run external converters with an external sample rate clock source. No problems or issues here. I keep my music collection segregated by SR (96k, 88.2k, 48k, 44.1k) as I ALWAYS listen through external converters.
The annoyance is when one forgets to keep track of core audio and inadvertently ends up listen to a piece of music sample rate destructed. You know - walk up to music server computer, forget that you had DAC set to 44.1k for last music played, put on 96k source, SRC takes over and you don't notice the artifacts and distortion for a few songs. No one wants that! Don't get me wrong - it's a convenient feature and the amateur user would be sunk without it.
What I want is an indicator that will tell when SRC is turned on and further, what the input and output sample rates are (as far as core audio is able to determine from the hardware anyway). In my world this would have been a check box in a preference setting. Perhaps someone has written a script or app for this? Command line instruction?
Thanks
