To play a stream audio file with external program...

Hi, I get with stream a sound file and I have to play it using an external program like VLC, reading the file continuously of a buffer. How can I do it? Would I have to controll VLC commands? I have been reading about it, but I have no idea how to do it.
Thanks.

One way would be that you implement and run an RSTP server and give its URLs to VLC, RealPlayer or whatever proper RSTP client program.

i cant find a way to upload and manage my own audio content on this sampler...

i uderstand , thanx...
i managed to open an audio file and placed it in the sampler,i can play t sample in the little keyboard in the zones section, howver i dont know how to play it with my controller... the sample shows in C1 on logic's keyboard but if i play C1 on my controller nothing happens... how can i fix this?

Work flow for syncing separate Audio files with Video files in FCP

It may be too late for me to use this workflow that I want with my current project, but I need to figure out what it is anyway for future reference.
Right now I'm editing a movie which is near completion. When we recorded the movie, the camera's deck recorded reference audio from the sound guy at 48k @ 16bit. This audio also went through an additional set of preamps which added a small amount of noise. So we don't want to use the reference audio because of it's low resolution and less clean audio. The sound guy recorded straight to his deck at 48k @ 24bit, besides the better resolution, his audio is noticeably better.
The camera deck and 'clapper' (I think that's what you call it) were not connected or synced. So the video files and the soundsguy's audio files are slightly different lengths, but at least have a 'clap sound' to manually sync to. And I don't mean that the audio and video files won't play in sync with each other, I mean that the soundguy always started recording before the camera, so his audio files have slightly different start and stop times.
Could I have synced the audio files with the video files before I started editing this project? If so, could it have been in the way that the soundguy's audio would be connected to my video files while editing? What would that procedure have been?
My current workflow right now is I have my finished sequence, I change the bit rate to 24 in Sequence Settings, and start manually dragging the soundguy's files to the sequence for every little edited clip. This is going to take forever, there are 99 scenes in this movie. Anyway, at the end of the day these sequences are exported as .omf files and imported into Pro Tools for audio post production.
I was not thinking to figure this out before I started editing the movie, this is unfortunate, a newb move in a decent production.
Anyway, I don't know if there is a standard for this situation or if I just opened up a can of worms for many possible workflows. Please comment if you have experience in this area or please refer me to any reading material.
Thanks for your time!

The normal workflow (besides manually syncing up before editing!)
is to have ' some ' way of auto syncing the clips.
So you must have common timecode.
With external audio, you can slave the cam's TC to the TC output of the BWF recorder.
Then you can use BWF / QT merge (one of my apps) to sync them, or use Sync 'n Link.
(another third party application)
If it is not possible cause you're shooting with a cam without a TC input, you can record the TC output on one of the audio tracks of your cam, and use FCPauxTC reader to decode the beeps and translate that to QT TC, and again use the former tricks to sync them.
It is difficult when you have never done it, but very easy once you get the hang of it, and it saves a huge amount of time to do it right from the start.
Have a look at the FCP aux TC reader here:

Streaming audio file over the network w JMF. How to know when the file end

Hi
I am streaming audio file over the network using JMF. I want to be able to know when a file end so I can close the streaming session.
Can some one please help
Thanks

If you put a ControllerListener on the Processor that's associated with generating the RTP stream, it'll generate an "EndOfMedia" event when the end of the file is reached.

How to export all tracks into audio files with the same duration

Hi everybody.
I am trying to export all the tracks into different audio files.
It's 10 soft. instruments and an audio track. I tried with "File>Export>All Tracks as Audio File but the result is 11 audio files with different lengths. As the song is 3 minutes and 20 seconds I would like every single track to be 3.22 sec long.
How do I do it? In fact, each track is composed not only by played instruments but also by moments of silence.
Thanks!!

The files are different lengths because each instrument does not stop playing at the same moment. It would accomplish nothing other than waste disk space if Logic appended silence to the end of each file in order to make each track the same length. The different lengths you see mean nothing because the absence of appended silence means nothing.
each track is composed not only by played instruments but also by moments of silence.
Naturally. And that silence is accounted for in your exported files, when the silence appears at the beginning of the track, and when it appears during the track. It just isn't appended at the end because that would be pointless. Consider this project, consisting of four tracks:
When I use the command File > Export > All Tracks as Audio Files, Logic will produce four files that look like this:
The files are not equal in length, which is perfectly fine. What's important is that they all start at bar 1, and will align properly when imported into some other program. So all you need is the command you already used: File > Export > All Tracks as Audio Files. In one step, it will produce all the files you need, and it will produce them correctly.
By using Bounce, you would be gaining nothing except extra work, because you would have to do it separately for each file you wanted to produce. With Export > All Tracks as Audio Files, you get all your files with just one command.

exporting tracks means that any panning or automation will not be rendered. So if you want the engineer to put up all of your tracks at unity gain (all faders at zero) and have your tracks & stems reproduce the mix you're hearing at your studio, use bounce, not export.
If you want to have your tracks & stems reproduce the mix you're hearing at your studio, there's no need to go to the extra effort of using Bounce instead of Export. You only need to enable (in the Export dialog) the checkbox "Include Volume/Pan Automation." This is explained on p. 1022. When you do this, any panning or automation will indeed be rendered.

How to play 5.1 audio files

I have ripped my The Crystal Method Legion of Boom DVD-A to 5.1 FLAC files then converted to Apple Lossless (ALAC) using either Amadeus Pro or XLD. The resulting m4a files play in quicktime and preview but won't even import in iTunes. The info properties of the file show 6 channels of audio. I have tried other settings when converting, (24bit, 16bit, AAC instead of ALAC) and the results are the same. Here is the funny thing if I change the filetype from m4a to m4v it shows up in itunes and plays and says in the channel info Multichannel. Obviously it shows as a video. Is iTunes yet capable of playing multichannel audio files? If so what is the best converter to show up as proper 5.1 surround?

I used to play multichannel quicktime .mov audio files with iTunes. AAC and AIF.But not 24 bit AIF.
You need a multi output audio interface for this.
iTunes can play AC3 files only on bought movies or with perian installed via optical out. But problems with jumping from one file to the next or changing audio tracks leading to complete hangs of iTunes made me switch to PLEX, which plays everything perfectly even DTS and 5.1 AAC files over spdf optical into 5.1 receiver.(Converting AAC to DD on the fly).
Back to your question,
if you have a multi output audio interface and Quicktime Pro, you can generate multi channel .mov files and define what track goes to what output.

How to associate audio file with progress bar

Hi all,
I have a case in which I need to associate an audio file witha progress bar. What I want to do is to able to play a audio file which will say " Process started.." Process going on" and process ends, and it shoud be synchronized with the progress bar. Is there a way to do this .
Please let me know
Thanks,
Ankit G
Solved!
Go to Solution.

Are you referring to a LabVIEW horizontal/vertical progress bar, which basically has a U8 integer constantly written to it? Is this in a loop as it fills up?
If so, there is an entire palette that allows you to play waveforms. As you're writing to your progress bar the number, you can keep checking what that number is (event or case structure), and when it hits particular values, you play particular sounds. Here is a screenshot of that palette.

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.

It seems that you do not understand the problem at hand. I can listen on a m3u list using iTunes, VLC and other players, but I wish to listen on m3u lists as streaming music when I am on sites such as eMusic. For instance, I cannot listen on sample music at eMusic, but must download it first. Thus, it is not possible to listen on streaming music with Firefox. On the other hand, Opera and Safari handle m3u streaming music very well.
Can you listen streaming music or samples at eMusic using Firefox without downloading m3u-list on your local disk?

Using CAN bus to transport and play the stream audio data

hello,
Just want to build a PC-Based control network using CAN bus (Ethernet not considered).The system is separated two parts , one is the front unit(FU), and the other is the centeral unit(CU). FU performs dialing-up number to the CU , and play the stream audio media data come from CU, CU monitor the telephone call activated from FU's user , send rm or mp3 data to the FU . I'd like to know if CAN bus could realize this function？ if it can , which hardware must be supplied ? Is there any suggestion that not use PBX to realize the voice (telphone) communication ? Please give an solution , your advise is greatly appreciated . Thanks.
David

Hi David,
the CAN protocol essentially just gives you the ability to transfer (broadcast) up to eight data bytes across the network at a maximum data rate of 1 Mbit/s.
There are so-called higher level (or layer) protocols that further specify the data exchange between a data producer can the consumer (DeviceNet, CANopen, etc.).
If your application is not tied to any of those protocols, that means you have the freedom to design all (CAN) nodes of your network, you can implement your own protocol based on the eight data bytes and the arbitration ID CAN offers.
For more information on the CAN protocol, take a look at appendix B of the NI-CAN Hardware and Software Manual, or visit the web site of CAN in Automation (CiA).
For your particular application you would need a CAN port on both the FU and the CU (preferably high-speed physical layer) and a PCI interface CAN card for you development.

"Use RAW files with external editor" greyed out for Photoshop CS2?

I've just upgraded from iPhoto 5, and the "Use RAW files with external editor" option in the advanced preferences is greyed out when I select Photoshop CS2 as my external editor (back in the General pane).
It works fine when Preview.app is selected. I can understand that pre-CS2 Photoshop wouldn't be available, but CS2 is capable of editing RAW images.
Has anyone been able to get iPhoto 6 to send a RAW image to Photoshop CS2 using this preference? I've written an Applescript to do it in iPhoto 5, but I'd rather use something cleaner...
15" PowerBook G4 Mac OS X (10.4.4)

Works great with Photoshop Elements, opens with Camera Raw. The issue is you can't save it so that iPhoto gets the changes.
You have to save it and then re-import. I tried all permutations of saving it in originals and modified folders in the library. No luck. The only thing I didn't try is to save it as a jpeg over the top of the full sized one iPhoto created on import.

Renaming audio files with increasing numbers.

I don't know if this is a Logic or a MacOS question but since it has to do with music I post it here.
I received three Cds with audio files. Every CD starts from track number one. I want to import all that files into logic. It confuses me when I have three audio files with the same name in my audio window. I want to rename them so I can see to which CD they belong.
I could rename all the files manually. But is there a way to rename the files with increasing numbers all at once?
Can I do that with the file manager or automator??
Thanks for help,
Eddie

Hi
what i do is import the files in Logic.
In the arrange window select all the different regions (i only have done this when they're on the same track).
Select the text tool.
click on the first track you wanna rename - a blue box will appear.
type the preferred name with a 1 after it.
all the regions following that region will be renamed incrementally.
You can also do this with a single region that you have split in logic.
Or you can split a region in logic and to rename them as individual files i press ctrl-F and ask logic to save them as "xxxfile1" - or with out the "1" i can't remember - and it saves them all incrementally.
Hope this helps

Export .m4a Audio File with Cover Art?

Hi, I recently upgraded to GarageBand 10.0.1 after purchasing a new MBP and have been mostly successful in finding all of the changes in the app, except this one. I use GB to create an audio podcast weekly, and in previous versions, I had the ability to export an audio file with the iTunes cover art already attached to it. I cannot find this feature in GB 10.0.1. Am I missing something? Thx for your time and any help given.

That is disappointing. Usually Apple is better about taking away steps to creating things, not adding to the number of steps required to create things.
GarageBand has been released a bit early. I am hoping, there is more to come. Otherwise, the installer would not have left the old version installed. It is a clear sign, that Apple knows, that some important features are still missing in GB 10.0. For the time being, I am starting the projects in GB '11, and add the finishing touches - drummer, arpeggiator in GarageBand 10.0.
