Weighting of Tone Generator??

Is the tone generator in Adobe Audition 3 weighted?
I am not seeing an option to create non-weighted sweeps.
I create a 32bit Float sweep from 10Hz to 22kHz.
Then do a frequency analysis of the sweep.
It is showing a small roll off in the low end. More like a low shelf really,
from around 150Hz and below, with a slope of more dB reduction toward 0Hz...
which reaches a final dB of around -4dB on that sloped shelf.
Or is the analysis weighted itself?
I will post a picture soon...

Not weighted, no - but what settings did you use? If you used a higher FFT setting, then it is quite possible that because any one sample slice will only be looking at part of the LF waveform, it will represent the overall level of this incorrectly. But like Bob says, if you use the default setting, you should get a correct analysis - within reason. Reason here being that it's also partly dependent on the type of analysis window you use, and they all have discrepencies at LF.But they are there because without them, the analyis would be possibly slower, and contain a load of rubbish you really didn't want to see. But it's these inherent errors that actually stop the analysis working at all at larger window sizes (smaller numbers).
I tried what you did with an FFT of 4096 and a Blackman window, and yes, you get a slight falloff of about 4.5dB from 50Hz downwards. But that's definitely the analysis, not the waveform. If you inspect the waveform at the bottom end of the sweep, you will find that the sine wave amplitudes are exactly the same as for the rest of it.
(I should add that I tried this with Audition 2 on this machine, but I think it's exactly the same on 3)

Looking for suggestions for specialized tone generator

An office colleague has two tuning forks: one is middle C and the other is G. When she strikes them and holds them near my ears for several seconds, one on each side, the effect is amazing. Then she reverses their position, to continue my nearly trancelike state.
I want to find an application that will duplicate this effect. I can't find a tone generator that will create two tones simultaneously, one on each channel, much less reverse channels at some point. I am guessing there are music or mixing applications that can do this effortlessly, but I am too dumb to identify them. Will some kind soul help me out? If no app is available I may try to develop an app for that and get rich.

In the waveform display, select the part of the audio file containing only the noise you want to reduce. Choose Process>Set Noise Print. The selected noise is stored as a noise print. Then, in the waveform display, select the part of the audio file in which you want to reduce noise (probably the whole file in your case), and choose Process>Reduce Noise. When the reduce Noise dialog appears, drag the noise threshhold slider to the right just a bit (I take it down to about -45db to -40db), and click the play button in that dialog window to preview the file. If you like what you hear, press Apply.
FYI, this was taken nearly word for word from the Soundtrack Pro user manual, pp168-169.
Happy denoising.

Mainstage 2 between keyboard and tone generator

I'm having some problems trying to do the following:
I have a keyboard (midi controller) and a tone generator. I want to create different controls that respond to the keyboard knobs and then send midi messages to the tone generator. This way I would be able to control the tone generator from the keyboard (and keep all the splits that I have in Mainstage).
Up to this point I can create knobs that respond to the keyboard movements; however I don't know how to create the actions so that messages are sent to the tone generator. Are there any resources out there that explain how to do this? Is it even possible?
Thanks!

Thanks, that was genius!
I noticed that this works well for simple requests. However, if you want to send a bunch of parameters through midi (for example changing EQ on one part of a performance being played by the tone generator), how do you do it? I read something about using sysEx librarian but it sounded quite convoluted... Is there a way to write the Midi parameters in a box and making sure is being sent out to the tone generator?

Test tone generator?

Hi,
Im doing some hardware amplifier repair work and I need a signal/function/test tone generator but I cant seem to find a decent working up-to-date one that runs under linux. Ive tried baudline_jack but it just segfaults when I hit record with the tone generator enabled. Ive tried siggen but it looks for /dev/audio or /dev/dsp (which I dont have) and it segfaults. Ive tried all of the arachnoid.com ones and the java script one does work but it is limited for my purposes in that it doesnt generate sweeps. Ive even tried looking for LADSPA and LV2 plugins but I couldnt really find anything. Basically im looking for something as close to this "Test Tone Generator" as possible.
Any Ideas?
Edit:
I can get by with using the arachnoid generators modulator instead of a dedicated sweep but I would still like to find a good replacement. THX

You don't have /dev/audio because ALSA's oss emulation modules aren't loaded by default. /dev/audio and /dev/dsp were created when I tried this:
# modprobe snd_pcm_oss
I don't know if this will get siggen working for you, I haven't tried it.

Example: Code to generate audio tone

This code shows how to generate and play a simple sinusoidal audio tone using the javax.sound.sampled API (see the generateTone() method for the details).
This can be particularly useful for checking a PCs sound system, as well as testing/debugging other sound related applications (such as an audio trace app.).
The latest version should be available at..
<http://www.physci.org/test/sound/Tone.java>
You can launch it directly from..

Any reason why you call getSourceDataLine() twice? ..Oh wait, I know this one (..snaps fingers. yes) it is because I am a mor0n, and forgot the class level (static) attribute declared earlier in the source when I (re)declared the local attribute and called getSourceDatLine (which was redundant, given the next line, which as you point out also called getSourceDataLine).
There are (at least) two ways to correct this problem.
1) Remove the class level attribute and the second call.
2) Remove the local attribute as well as the first call (all on the same code line).
Method 1 makes more sense, unless you intend to refactor the code to only instantiate a single SDL for however many times the user presses (what was it? Oh yeah..) 'Generate Tone'.
My 'excuse' for my odd programming is that this was 'hacked down' from a longer program to form an SSCCE. I should have paid more attention to the fine details (and perhaps run a lint checker on it).
Thanks for pointing that out. I guess from the fact you spotted it, that you have already corrected the problem. That you thought to report it, gives me confidence that you 'will go far (and be well thought of, besides)' in the open source community.
..This is quite handy, thank you.You're welcome. Thanks for letting us know about the error (OK - the pointless redundancy). Thanks to your report, other people who see this code later, will not have to wonder what (the heck) I was thinking when I did that.
Another thing I noted, now I run the source on a 400MHz laptop (it's hard times, here) is that the logic could be improved. At the speeds that my laptop can feed data into the SDL, the sound that comes out the speakers approximates the sound of flatulence (with embedded static, as a free bonus!).
Edit 1: Changed one descriptive word so that it might get by the net-nanny.

Unrendered Bars and Tone (NTSC) in Generator

Hello,
I've had this strange problem for awhile now and cannot find a fix. My NTSC bars and tone generator from the viewer comes up as "Unrendered" in the Viewer and when I print to video, yet the tone is still good. All the other generators are working fine.
To try and fix this I have reinstalled several times, restarted many times and tried all manner of exporting, etc. Where can I go to correct this? I've searched the forums and internet and gotten no results.
Any help appreciated.

"Unrendered" in the Viewer window? Your FCP install is losing it's marbles.

Is there a way to set up a dial tone or a way for someone who is hard of hearing to have the phone set up to make a noise when I hold it up to my ear?

Is there a way to set up an dial tone or set the phone up to make a noise when I hold it up to my ear when i use it

I'm also not sure what you want to accomplish by this. Until you hit the "call" button, the phone is not 'off hook' like a traditional landline would be. There is no such thing as a dial tone on any cell phone. The dial tone was simply a carrier signal from the central office that prepared that end to listen for the pulses (later tones) generated when you dialed.

Multitone generator with more inputs and with output to computer speakers

I want to add several (perhaps 10) harmonically related sinewave tones and output to the computer speakers or line out. Ideally would like to use the full audio range so 44100 Hz sample rate. I've managed to combine a couple of VIs and get something that works at lower sample rates but doesn't dynamically update if I change frequency or phases. And at higher sample rates it isn't a continuous sound. It just beeps, then waits, beeps then waits. I'm sure oters have tried to tackle this in the past but don't find much info. Currently using a Mac but could switch to a pc if needed. Guidance will be most graciously accepted.
Solved!

Dans Multitone Generator with amplitude and phase.vi ‏59 KB

I found several things which together keep your VI from working the way you want. The VI attached works fine on my Mac.
1. I configured the sound and the tone generator to use the same sampling info. Any other combination creates complications.
2. I found out the hard way that the tone generator wants the frequncy to be an integer multiple of (sampling rate)/(# samples). This does not appear in the documentation (help file) but other combinations throw errors.
3. Set the amplitude input (not Tone Amplitudes) on the Multitone Generator.vi to 1.00. This makes its output compatible with the Sound VIs. This is documented in the help but you have to read several places and put thepieces together.
4. The reset input to Multitone Generator.vi must be true for it to respond to changes in the tone frequencies, amplitudes, or phases inputs. I just wired a true constant for now. Later this might be better handled by an event structure.
5. Consider making the frequency, amplitude, and phase controls into arrays or one 2D array so that an arbitrary number of tones cna be used without modifying the program.
6. Some kind of Wait may be required. Without it I occasionally received a Timeout error. Several options are in different cases of the Diagram Disable Structure. The Sound Output Wait will guarantee that the timeout does not occur but it also produces small gaps in the sound. The Wait (ms) works fairly well but it is a guess as to the optimum value for the Wait. After all the changes I have madevene the no wait case seems to work.

Roger "Beep" tone after audio file

I have a question; I have received VO files that have been recorded on Audition 5.5 & 6 and they have a "roger beep" (may be the best way to describe it) between each "take" Its used as an indication to separate or end a recording of that script before going onto another. It is in fact a double beep beep similar to a walkie talkie when releasing the send/transmit button. I have Googled the effect but only Protools seems to have a plug in for this... Can you assist in making me wiser?

Audition is perfectly capable of making all sorts of beeps and tones on its own - although I think you may have to manufacture a short file of the one you want. You will then be able to insert this as many times as you want in a multitrack session. Chances are that whoever sent you the files did exactly that (except that this would have come from Audition 6, as 5.5 didn't have the tone generator put back in it).
The way to do this is with Effects>Generate>Tones. If you generate 1 second of a suitable tone, you can select the segment from 0.15 seconds to 0.5 seconds, and then go to Effects>Silence and silence that section. Then select the tone from 0.65 seconds to the end of the file, and similarly silence that. Play the result and it goes 'beep - beep'. Save the result, and you have a roger beep file that you can interpose wherever you like. If you don't like my timings feel free to use whatever timings you like. As for the tone itself, stick with sine waves and don't run them at more than -3dB. Frequencies suitable are probably between 440 and 1000Hz.

Anyone have a Multi Instrument setup for the MO6?

I just got a MO6 workstation to integrate into my studio
setup. I was wondering if anyone has this keyboard
(or the MO8) and has a Multi instrument for it setup
in the enviroment. I am trying to not have to input
all the names of all 16 instrument banks. I tried
doing an Google and forum search with no luck.
The thing is impressive sound wise and will be
easier to edit with the free software available.
Only wish Apple would get their support online.
Yamaha did thier end with the remote control
feature. I can put it into Remote control with
one touch and start controlling Logic from the
keyboard. Every button has a dual role, one for
the workstation and one for Logic. Very cool feature.
Thanks in advance, Phil

Sorry, I only have the original Motif 6 environment,
but I wanted to ask you how you like the MO6?
Have you used the original Motif at all? I'm thinking
about saving up to get a MO8 because of the weighted
keys, and having the ES sounds only helps.
Thanks for posting,
I have not used the original Motif at all but am loving the MO6!
I am primarily a guitar player but since getting this board my inner
keyboard self is coming out. Sound On Sound has a review of
the MO6 in Junes issue. I recieved my copy a week after purchasing
the MO6 and was glad to see their positive review.
I would recommend the MO8 for the tone generator alone and as SOS put it,
you got to love that arpegiator! Everything else to me is icing.
I will have to check out the Motifator web site. That is probably my best
chance at getting the enviroment for the MO6. Thanks again for taking
the time to post.

Yet another problem getting a .jar file working on Mountain Lion

The program I need to run is used for generating sounds. Its a simple java program, set up in a Windows .msi container: http://innertotality.com/?q=node/9
I currently have the most up to date Java build from Oracle, according to their online test: v7 update 15. However, it shows up in Terminal after a java -version command as 1.6.0_41.
Whatever version it is, I can't get this program running on it. I've pulled the .msi file apart to get the cab file, pulled that apart to get my jar file, in this case "headwave.jar". Clicking on it makes the JRE icon appear in the dock and do its dance, then it closes down. I can repeat that all I want and never get a running app out of it. I've opened the console up and watched for messages. This is all I've managed to get:
2/23/13 9:58:44.218 PM login[2871]: USER_PROCESS: 2871 ttys000
Nothing more, and I've only seen that once. I get more out of Console simply dragging a word around in this box to edit this post.
If anyone could shed some light on what I need to do to get this running, I would greatly appreciate it. There are very few Mac OS X sound tools available to do what I need so this is really holding my project back. Most everything out there has to do with professional or amateur audio editing, not pure tone generation. I tried ToneGen and it just isn't doing what I need, and Perfect Tone and Tone Generator X haven't been updated for Intel Macs.

No I haven't, but I just tried it. I tried to cd to the desktop (worked), found the Headwave folder with ls and then cd into it, found the jar folder I extracted earlier (disk1), cd into it, etc etc. I found HeadWave.jar and knew I had the right directory. java -jar HeadWave.jar gave me the following:

How do I hook my Keyboard up to my computer to use it as a MIDI controller?

Ok, I'm new to MACS and new to LOGIC. I just installed logic and all of its components on my IMAC. OSX 10.6.3 Once I installed everything, I tried to hook up my electric piano to use it as a MIDI controller. Mind you, I am also completely new to MIDI. My Piano is a KORG sp-300. I used an Alesis Audio Link USB- MIDI cable to connect my keyboard directly to a usb port in my MAC. I hooked up the midi side of the connector to the midi in and out on my keyboard, and plugged in the usb side to the computer. I then went to the Audio Midi set up, and looked in the midi studio, and there was the USB2MIDI(which is associated with the Alesis cord, and not my Korg piano) and the IAC driver from MAC. I checked so that both are online, and didn't change any of the other settings. I did a test set up, but when I played notes on the keyboard nothing happened.
So now when I open Logic, or garage band for that matter, it doesn't recognize that I have a midi controller hooked up. When I look in midi preferences in garageband, it says that there are 2 midi devices detected. In logic it says that there is no input or output.
I read the manual for LOGIC and for my Korg, and I am lost. Korg says that it transmits on 1 channel, automatically set to channel 1 if not adjusted, and receives on 16. If I am correct, right now I am not interested in receiving, only transmitting.
At this point, I just want to select a software instrument in Logic, play my Korg, and see notes(or MIDI data) appear in the arrange area. I don't know what's going on, but again, I am completely lost.
Could someone please help me here? Am I missing an obvious step? Like I said, I am new to all of this, so please let me know if you have any idea how to get my midi controller to work. It says in the Korg manual that it can be used as a controller, or a multitimbral tone generator. And I did switch the Local Off.
By the way, who would be best to call to solve this issue. MAC? Sweetwater(where I bought the Alesis cord, and Logic)? Or Korg?
Please let me know if you have any helpful advice.
Thanks,
Tristan

Pancenter,
Thanks for the response, but I do not have a midi interface. I am using a midi to usb connector cable, thus bypassing the need for a Midi interface.
The Mac reads the USB cable as a midi device, but not the keyboard that I am trying to use as a controller. I have tried it with my korg sp 300 and with my Nord Electro 2.
Thoughts?
Thanks,
Tristan
Tristan...
This is what you have, correct?
http://www.alesis.com/usbmidicable
This from Alesis..
"The AudioLink Series USB cable receives and outputs MIDI signal thanks to its internal interface. The USB-MIDI Cable connects plug-and-play to your Mac or PC for an all-in-one USB-MIDI solution."
Notice, -internal interface-. What you have is a simple USB MIDI Interface. Most MIDI interfaces are USB.
My point is (was), MIDI OUT of the Korg goes to the connector marked MIDI IN on the Alesis, those new to MIDI often get this wrong.

3241 ISDN Gateway--DTMF Relay Type & local vs. national signaling

Question 1:
Is there a way to configure the 3241 so that it will flag local vs. national call types on the d-channel appropriately? The local TSP sees all calls flagged national.. They do accept both 7 and 10 digit formats for local calls so we set dialing rules to add the local area code (without a +1) to 7-digit numbers and that seems to work OK.
Querstion 2:
Does anyone know what type of DTMF relay is being used by the Cisco-acquired Tandberg/Codian 3241 ISDN Gateway? I'm pretty sure the DTMF relay type is not configurable in that box. Does this fall under the alphanumeric H.245 relay type?
I have a customer that, for outbound long distance calls (Primarily ISDN voice, but some ISDN video), requires their ISP to provide a DTMF-based billing code service. We've worked with the local TSP to verifiy what they are seeing on the switch and it looks like all digits are passing appropriately (although I also don't see any way to tell the Cisco 3241 GW to flag the call as Local vs. National
The PRI itself is provided through one local LEC and handed to a secondary TSP to provide the DTMF/billing solution.
The PRI has been works fine for local calls, but long distance (national) calls route throuth the primary provider and then pass to the secondary provider. We've worked with the local TSP to verifiy what they are seeing on the switch and it looks like all digits are passing appropriately. Logs from the ISDN gateway do not show opening any audio or h.245 channel, no 'biiling tone-prompt' is heard, and we cannot access/enable the touch tone menu on the endpoint during the time the ISDN GW is attempting to set up the call. I suspect that either the billing code service is not turned up yet, but I'm hoping its is not a H323/H.245 and/or endpoint cpability that is preventing this from working.
In order to troubleshoot with the service provider I assume I'll need to know what DTMF type we are sending, I am hoping they could also tell me by debuggin the switch for any signaling they are receiving from us.
If anyone has any experience setting up similar service on CUCM i'd love to hear what was required on that system for DTMF relay, and if there is anything else I may need to ask the TSP
Thanks!

DTMF relay for H323 is handled with 3 commands.
cisco-rtp Cisco Proprietary RTP
h245-alphanumeric DTMF Relay via H245 Alphanumeric IE
h245-signal DTMF Relay via H245 Signal IE
Your best bet is h245-alphanumeric. The dtmf-relay rtp-nte command is used for SIP dial-peers.
The DTMF relay feature transports DTMF tones generated after call establishment out of band using either a standard H.323 out-of-band method and a proprietary RTP-based mechanism, or for SIP calls, an NTE RTP packet.

Bridge just fine. But the Sound Effects included in the Presets of AE don't
appear to be valid files.
Is this a known issue or am I going to have to reinstall something?
Thanks!

ah .. thanks, Steven .. I'll give that a try. Much appreciated! Nancy <[email protected]> wrote in message news:[email protected].. > Weird, I've never even noticed those.

Sine waves, sidechaining, and a deeper kick drum question

Hi all,
I found the following tutorial on sidechainng a sine wave to create a deeper sounding kick drum and tried to do it, but I'm going wrong somewhere.
http://www.generate-music.com/QT/L8_SinewaveTutorial.mov
He says to use a test tone generator to create a sine wave at 55 hz and export that as an audio track. I'm not quite sure how to do that. I saw a test oscillator plug-in when you create an audio track, so I set that up to about 55hz and hit record, and it just gives me that test tone but it doesn't look like anything recorded.
Also, when he puts the Channel EQ, Expander, and Noise Gate on the Aux 2 audio track, I see a "SineWav..." channel strip setting with those 3 plug-ins...is this an existing strip setting that I just can't find, or did he manually place the 3 plug-ins and then save it as "SineWav..."?
Any help is appreciated! Thanks!

Hi,
You can export the 55 Hz sine wave, just do a new empty session, create an instance of the tone generator, set ti 55 Hz, turn it up (lower the volume of your speakers) and bounce a few bars of it.
Then you'll have your 55 Hz audio file ready for use. Import it into the session you'll want to use it on.
As far as the channel preset, he robably made that one himself. No worries, just match what he did.
Cheers
