Quicktime Broadcaster AUDIO Input Level Setting

Greetings all,
I'm trying to record my band's rehearsal w/ QtB, but even when the Audio Gain level is on 0, but I still get distortion when playing back the recording.
Are there any ways to fix this?

Go to your system preference. Sound Prefs...Make sure your not taxing you sound. There is a control for input setting...

Set audio input level manually on t5i

First post here. I've just started workig with my new t5i, which I'm using to work on my ongoing video tutorial series. In the manual I see how it is possible to set the audio input level maually for an external mic but I can't figure out how to navigate to the menu that allows me to do this. I have pored over the user manual a number of times and can't find this information. Can anyone help?
Solved!
Go to Solution.

Same camera in different shooting modes. The menus I described would be for shooting video in "P, Tv, Av, or M". Anything else will give you a smaller menu selection like you have already seen.

Recording audio : Input level automatically compressed?

Hi,
in my short experence using Soundtrack Pro, I have never been able to get an input level positiv (yes I know that it means "saturated").
Is the audio signal automatically compressed if it exceeds 0dB ?
Thanks for your help.
Eric

It all depends on the dynamic range of your source.
I usually record around -12 db average if I'm in a controlled environment. -20 db if I'm out in the wild. This gives me enough headroom so that unexpected transients don't blow things out.
If you want to record things hotter, you need a dedicated sound person listening through headphones to ride the levels.
I usually work in video. In that world, broadcast output specs often call for -20 db or -12 db as average levels. All those anoying locally produced commercials are running audio up around -6 db.
If you are recording and mixing music for CD production, audio levels are often captured as hot as they can without clipping. Then, they run the signal through a compressor/limiter to boost the average levels as high as possible.

Flash Media Live Encoder 3 Audio Input Level Resets (XP)

I am using Flash Media Live Encoder 3 on a Windows XP computer, with an Ospery-100 capture card for video and a generic sound card line in for audio input. It works fine, except for every time I launch the encoder or even just stop and start encoding (i.e. without closing the application), it resets the line in audio level of my sound card to maximum--not good, as the appropriate setting is actually the minimum. If I don't remember to open the Windows mixer and turn it back down, the audio clips like crazy. No other application I use changes the input leve of my sound card in this way. What is happening here? Any ideas? Any solutions? Thanks.

Have you checked volume slider position in FMLE? If it is set at 100% it would increase the audio level of sound card. Drag slider to lower value to reduce the volume level.

Why would audio input level go very low?

I'm sure I've done something dumb but I can't work out what it is. I'm recording with a mic into my laptop and the sound is really quiet.
I've used this set-up loads of times without this problem: Audition CC, Rode shotgun videomic into MacBook Pro.
Anyone know why the volume would now be so low please?

In Audio Midi Setup the levels are greyed out, and in any case set high, at "Value = 0.917" and "dB = 10".
We can rule this one out straight away - MIDI (Musical Instrument Digital Interface) has nothing whatsoever to do with this!
Likewise, in Preferences > Sound the input level is near the top.
I think that you need to find out what the input socket thinks it's doing here. What Bob is suggesting is that if it's a dual-purpose socket (ie it doubles up as either a line, or a mic, input), it's stuck on Line. And that's no good for a mic - far too insensitive. We're both a bit stuck at this point though, because it's a Mac you've got, and neither of us uses those...

Quicktime and Audio inputs.

Hi everyone,
thanks for your time.
I need to record some fast videos with my macbook pro and I want to use Quicktime because it is really fast and easy to use.
This is the problem.
When I start to record a new video and I select my "Focusrite Pro 24DSP" as main audio interface, Quicktime records only inputs 1 - 2.
How can I choose other inputs, like 15 - 16 (where it is the loopback function), or simply record the Mix Out?
I need to record my keyboard along with some songs on iTunes.
I tried to go into the audio preference, but I can't do anything for the inputs. I am asking if with another audio interface, like an Apogee duet maybe, I can resolve this problem (I can select which channel to record! 1, 2, 3, 4... or the DAW, or MIX L - R).
I could do this with my windows XP and with a 30$ USB interface (I could select the mix as record input from the audio preferences).
Why can't I do it with a 1500$ Macbook?
I don't want to use Logic Pro for this (it works good): I need a fast video - audio record, but I just have to record the complete mix (L - R), not only 1 - 2 inputs.
I hope that everything is clear!
Thanks for your help,
Marco

I just did my first feed Monday night. I used a video mixer and Mackie board myself. I feed the audio and video(component) into my DSR-20 VCR, which I also use for a tape backup recording. This then feeds the QT Broadcaster. I don't think you can feed anything but a firewire machine or iPhoto camera into Broadcaster. Might work with an USB camera/vcr???
I feed H.264 video, at 320x240 with mono 16 bit audio. Hint... don't do disolves, as they increase the frame rate. simple cuts-only seems to be the best. We also fed keynote slideshow into switcher... carefull there, as it produces saturated colors that will effect the signal... the switcher will think the super saturated video is sync and glitch the video. red is the worst, of course. Next week I am going to use a little proc amp to drop the chroma a bit.

Mac Mini USB Webcam Audio Input

I purchased a Mac Mini a couple of months ago and set it up with HDMI to HDMI connection to my Samsung TV. I then purchased a Logitech webcam V-UBU48 and connected that to the USB on the Mac Mini. All was fine and I used Skype on this combination with no problems for a couple of weeks, using the webcam as both Audio and Video input device. Sound output was via the TV.
I then went on leave for a couple of weeks and on return set everything up again as it had been before. This time there is no audio input from the webcam and changing settings in Skype preferences or Midi utility does not seem to have any effect, The webcam is recognised as "Unknown USB Audio Device", but doesnt seem to work. So far as the Mac is concerned the video side recognises it as a Logitech Webcam and still works perfectly. Sound output via the TV is also still fine.
Since my return the only change that I can identify is the latest Snow Leopard upgrade to 10.6.4
The other issue is the volume control on the bar at the top of the screen is grayed out and does not function any longer.
Can anyone help identify the issue here. Thanks in advance

Thanks for the suggestions. A few hours after posting my issue I switched everything on and all was as before. I could control the audio input level in system preferences and use the webcam for skype calls as before, using it as the audio and video input device.
Now I have swithched the machine on again and it seems to have reverted back to the same problem as described in my original posting......very frustrating. Nothing registering on the sound input levels in system preferences. Tried restarting several times without success.
The Midi settings for the "Unknown USB Audio Device" i.e. Webcam are as follows:
Source Default (Grayed out)
Format 48000 Hz 1 ch 16 bit
M Channel volume slider is at the mid point, Value 0.49, dB 18.28, Mute and Thru both unchecked
I Channel slider grayed out and all else blank.
Since everything started working again I haven't touched these settings so I assume that they are the same with or without the issue.
I know issues that occur randomly such as this are least likely to find a solution but further suggestions welcome.

Help using Quicktime Broadcaster

Alright, so we want to set up a small, live internet broadcasting of some church services. We're still trying to figure out how to do this though. We're going to use my Macbook and use Quicktime Broadcaster. How do set my application up to send out the audio stream and how do others connect to the stream? Also, do the receivers have to be Mac users with Quicktime Broadcaster or can it be PC users with Winamp or Quicktime for Windows or Windows Media Player?? Any help, suggestions about other programs or alternative ways would be much appreciated. Thanks!

Webcam/Audio Input

I am admittedly an amateur at Actionscript, but I'm trying to
produce an example of Flash's ability to process video/microphone
data as a "jumping off" point for other projects. My problem is:
I am using some open source to pick up web cam movement and
produce a matrix based on such. I have added the code to receive
microphone input, which worked in the example (provided at
kirupa.com) that I composed on my machine. I am trying to replace
the "dot_mc.1=255" value with the microphone activity value
(0-100?) yet I am getting a response of "The property being
referenced does not have the static attribute." I understand this
statement, but I am unsure as how to re-form this statement to
accept variable data.
Here is the code so far:
import flash.display.*
import flash.geom.*
mic = Microphone.get();
_root.attachAudio(mic);
mic.setUseEchoSuppression(false);
function initialize()
setInterval(this,"snap",100)
this.createEmptyMovieClip("snap_mc",this.getNextHi
ghestDepth())
snap_mc._x=(Stage.width/2)-(scale*w/2)
snap_mc._y=(Stage.height/2)-(scale*h/2)
m=new Matrix()
m.scale((output._xscale/100),(output._yscale/100))
now=new BitmapData(w,h)
rt=new Rectangle(0,0,w,h)
n=0
for(x=1;x<w;x+=o)
for(y=1;y<h;y+=o)
++n
dot_mc=snap_mc.createEmptyMovieClip("dot"+n,n)
dot_mc._x=x*scale
dot_mc._y=y*scale
dot_mc.lineStyle(dblo,0x000000)
dot_mc.lineTo(0,1)
function snap()
var c=0
now.draw(output,m)
for(var x=1;x<w;x+=o)
for(var y=1;y<h;y+=o)
++c
nc=now.getPixel(x,y)
nr=nc>>16&0xff;
ng=nc>>8&0xff;
nb=nc&0xff;
nl=Math.sqrt(nr*nr + ng*ng + nb*nb)
bc=before.getPixel(x,y)
br=bc>>16&0xff;
bg=bc>>8&0xff
bb=bc&0xff
bl=Math.sqrt(br*br + bg*bg + bb*bb)
d=Math.round(Math.abs(bl-nl))
dot_mc=snap_mc["dot"+c]
if(d>tolerance)
dot_mc.clear()
dot_mc.l=255
dot_mc.lineStyle(dblo,255<<8)
dot_mc.lineTo(0,1)
dot_mc.onEnterFrame=fadePixel
updateAfterEvent()
before=now.clone()
function fadePixel()
this.clear()
this.l-=this._parent._parent.ml
this.lineStyle(this._parent._parent.dblo,this.l<<8 )
this.lineTo(0,1)
if(this.l == 0)
delete this.onEnterFrame
Altering the dot_mc value varies the colors of the webcam
matrix dots, so I just need the activity level on the microphone to
act as the value and perhaps multiply it by 2 (since the dot_mc
value can be up to 255).
Any Ideas on how to repair this?

Quicktime Broadcaster - getting it online

I'm trying to work out how to stream my webcam live onto my website.
I have installed QTSS and Quicktime Broadcaster, and managed to set it up so it can be viewed around my home, but I have no idea how to get it out and onto the internet or embed it into my site (after a LOT of searching Google).
Can anyone explain?

We were using two Canopus ADVC110 Video converters as I have medical use which is allowed for these devices. This is also the reason I cannot use other video converters at the moment. We were streaming H.264 only as plain MPEG4 would not have met our bandwidth restrictions without serious danger of massive dropouts. (A different story, not QuickTime's fault.)
With a Testbild (bars and tone) I actually didn't have a problem, even for prolonged periods. Maybe because the Testbild was came from the SONY betacam we used. Quality was nothing short of stunning. With the ultrasonic echo-scanner image locked I experienced problems with the upstream breaking after a few minutes. Maybe also because this stream was video only.
I'll try and experiment with UDP upstreaming if that helps with the disconnects.

IRig input level for vocal mic extremely low

Hi All,
I have ben merrily using my iRig and Garageband for Ipad to record instrumental tracks with no problem, but recently decided to try and add vocals. Just to test it out I bought an imitation SM58 style dynamic mic, with an XLR to jack lead so I could use the iRig, however when I go to use it, the audio/input level for the mic is VERY low - any ideas as to why this might be? I've turned the track volume and input up to maximum but it's still barely audible. Suspect it might be the mic, so tempted to spend some real money on a condenser mic, but worried I will get the same result. Are there any alternatives / success stories with recording vocals through Garageband, and what are you using?
Thanks
Nick

I have used the Shure SM58 and many microphones similar to it in studio and live settings, and that microphone requires what is called Phantom Power when it is run through a mixing board. In a nutshell, Phantom Power runs 48 volts on the channel the microphone is in, because that microphone only sends a passive signal and it needs to be powered. So the reason your microphone would put out such a low level would probably be because there's not a substantial for your iRig to pick up, even at maximum gain. I would look into purchasing a phantom power unit or some other preamp that you can put between your iRig and microphone.

Separate audio and video inputs for Quicktime Broadcast?

I want to produce some real time streaming via Quicktime Broadcast. My audio will be coming from a Mackie mixer with firewire interface, the video will be coming from my video switcher which has a firewire output. Will I be able to combine the audio and video firewire feeds in the computer (or software), or must I combine the audio and video into one firewire feed before it hits the computer?
Thanks!

Setting input level when recording

Is there a way to set the input level in Audition when recording? I can't seem to find it if it's there.
Here's the setup: Audition is installed on a new Dell Vostro (plenty of RAM and speed) with an M-Audio Delta 1010 LT card. The input is coming directly from a broadcast console at a radio station. Audition is used to record incoming phone calls along with the DJ's mic for playback later: DJ mic on left channel, incoming call on right channel.
Broadcast consoles are different beasts from recording consoles. The input channels of a broadcast console do not have variable/selectable pads or gain... so the audio signal is fairly hot.
The 1010 LT card has a "control panel mixer" but it seems to have no affect whatsoever on the input level. As a result, the signal clips when it's recorded into Audition.
So... is there a way to set the input level in Audition when recording?

If you are using a soundcard with input from pro console you need one that accepts pro levels I'm afraid! You will need to attenuate the input to the Delta 1010 by some external means like inline 10 - 14dB attenuators for instance.

Send Mac streaming audio (Quicktime Broadcaster)

I am using QuickTime Broadcaster and I have a streaming audio to the audio currently being played in the mac (not the microphone, not the line input) if not the audio currently being played by the mac, but I did not know how to do this, can someone help me? thanks in advance

The audio found on a CD is recorded using 44.1 kHz.
Your DV camera records at 48 kHz only because that is the setting used in .dv files.
It's a waste of bandwidth to use such a high setting. Heck. You probably don't even need "stereo".

Setting Input Level with Griffin iMic

I'm trying to digitize an audio cassette with Soundtrack Pro. My setup includes a Griffin iMic that goes to a USB port. The trouble I'm having is in controlling the input volume. The level meters indicate clipping, but I'm not clear how to set the input level.
If it's in the Recording tab (>Input) with the Gain slider, mine is greyed out.

M Wohlgy,
(I know this is months after your post.)
Control of the iMic volume is in the Preferences pane called "Sound". You can set the output and the input levels there.
Remember the iMic's position switch works only for the imput, either close to the microphone icon for "microphone" or away from it for "line in".
I use the iMic exclusively.
