Settings/discontinuity of SineWave

Hello

Is it possible to have two sinusoids that play one after the other would accuse discontinuity? I know that I can can use the setting Phase and calculate as follows:

y = Amplitude_A * sin (frequency * time + Phase_A)
Bias_B = Amplitude_A * sin (frequency * time + Phase_A)

Since time = 0:
Bias_B = Amplitude_A * Sin (Phase_A)

Insulation Phase_A:
Phase_A = ASIN (Bias_B/Amplitude_A)

(and I convert it into degrees)

So I have a function that is as smooth as possible, but it does not work if I have a sine wave of 800 (max) 200 (min), followed by another 600 (max) to 400 (min). If my bias is higher the Amplitude (just as in this example), I have no way to go at the end of the first sine wave at the beginning of the second without discontinuity or ramp. Ideally, I'd like the transition for a curve.

Sorry if this is not clear, English is not my first language.

Thanks in advance

Hey PPrez.

I think the only way to ensure that it will not be a discontinuity for make sure that you have the sine wave to a point common. Since we are not changing the frequency and that we are not changing the focal point of the amplitude (500 in two waves), the best way to get this change with minimum discontinuity is to change to cross this line 500. There is no necessary dephasing, because point central it should be phase 0 and pi of two waves depending on whether you cross low to high or high to low. You can also implement fenestration during the transition period to minimize discontinuity, but this will change the shape of your signal during this period.

  • Scanning PC settings appears every day

  • Is there a way to read the settings in a .pst file?

    Hi all!

    I looked everywhere for info on this and found nothing. Anyone know how to read the settings contained in a .pst file? I found some that I really like, but would like to know what they are doing. In other words, what are the different used FX and what are their settings? I would use some other users have created as a starting point to create my own channels of FX. Open in a text editor doesn't show something like:

    @^@^@D^@^A^A^@^@^@^@^KEMAGPPST^@^@^A^H^@^@^@^@Âp^@^@^@^@^@^@^@^@^@^@^@^@^@^@¿< 80 > ^ @^ @^ @^ @^ @^ @^ @^ @^ @^ @^ @^ @^ @^ @? < 80 > ^ @^ @@ ^ @^ @^ @

    Is there a way to show somehow what they do and what they use the settings?

    Thank you!

    You're right, the settings file contain only of the code when opened in a text editor.

    But why don't you just open settings in a project, this way of seeing exactly what Plugins are loaded. Opening of the plug-in window will show you their parameters.

    The only restriction is that GarageBand has only a limited view of Plugin window which can not show all settings. To do this you must open in Logic Pro X.

    Hope that helps

  • Impossible to change the settings for the overlap of the midi regions

    Hi people

    Trying to change my project settings so that my midi regions overlap or merged.

    However, when I select the different options in the project settings - setting won't change even after choosing, he. All the default to replace & I can't change anything...

    Any ideas?

    1 - ability to select IMAGE options, but as soon as I click on it it goes back... (see image 2)

    IMAGE 2

    Weird. Since nobody had a suggestion again I'll propose to eliminate most bizarre factors:

    -Check the permissions to read / write to the project folder, you are working, and where the logic is in. You have full access?

    -Detach the Audio interfaces / external MIDI, reboot and external logical beginning without entries/connections

    The same problem happens for tracks Audio parameters too?

  • Settings lost VPN - iOS 10.0.2

    I had stored in my iPad VPN settings. VPN connections worked well until the latest iOS update. Now ALL my VPN connections disappeared. To make it even worse-, I am unable to put once again, because there are new mandatory fields: VPN type and shared key. I don't have the slightest idea how to fill them because I never need them when connecting to the VPN through my iMac - please see the screenshot.

    It drives me crazy. I welcome any suggestion.

    Prepare for removal of PPTP VPN before upgrade you to iOS 10 and macOS Sierra

    Preparation for iOS system administrators 10 and macOS Sierra should stop using PPTP VPN connections. Learn about alternatives, you can use to protect your data.

    If you have configured a PPTP VPN server, 10 iOS and macOS users Sierra will not be able to connect to it. iOS 10 and macOS Sierra will remove any profile VPN PPTP connections when a user upgrades from their device.

    Even if the PPTP protocol is always available on iOS 9 or an earlier version or OS X El Capitan and earlier, we do not recommend that you use it for secure, private communication.

    Alternatives for PPTP VPN connections

    Try one of these other VPN protocols for authentication by user that are safer:

    • L2TP/IPSec
    • IKEv2/IPSec
    • Cisco IPSec
    • VPN SSL clients on the App Store, such as those of AirWatch, Aruba, Check Point, Cisco, F5 Networks, MobileIron, NetMotion, Open VPN, Palo Alto Networks, Pulse Secure and SonicWall
  • Search iPhone settings for "Auto-Lock" does not work

    Hello

    Does anyone know why the Auto-Lock setting is not to be found when you use the search at the top of the main settings page.

    From time to time, when I'm on a conference call, I like to set the auto-lock on 'Never', so I can leave the visible main phone screen to mute/one-mute the call without having to unlock the phone. I have the memory of a goldfish, so I do not remember that it is in the section "Viewing and brightness" and that is why I use the search at the top of the main settings page field. I would normally enter 'Auto', and it would be "Auto-Lock" for me.

    Since the release of iOS10, the la recherche search can't find this definition more although it still is in the section "viewing and brightness.

    The search for other settings seems to work, but it seems that it is just this one, but I have not actually tried too.

    Any ideas on what is happening and how I could get to find the Auto-Lock in the future?

    Thank you

  • Problem with 10.10.5 security settings

    I'm on 10.10.5 Yosemite on an iMac.  I'm trying to give a program permission to control my computer under Security & Privacy / Accessibility.

    When I click on the padlock at the bottom left to 'Edit' and input my user and password, it does not reject the entry as incorrect but it never unlock the field of accessibility for me to make changes.  I don't know that I did this exact process before without problem so I'm confused as to what is happening.

    I tried in two accounts different administrator and nor will I can unlock the lock or little down in the left corner to make changes for accessibility.

    Any ideas?

    I would add just after that I got my admin info there is a very brief moment where the accessibility settings appear to unlock and then it crashes again.  (like maybe 1/3 of a second).

    Also, I restarted the computer one or two times to see if it would make a difference... No.

    By default, the settings are WPA2 Personal. There should be no need to change it.

    To view the settings and make changes to them, you need to open the AirPort on your Mac utility.  Are you still using OS X (10.6.3) you specify in your profile?

  • Deselection of voice on improvement in Inspector restores the default settings.

    Voice more improvement is a combo of compressor, deEsser, and EQ sound effect. I changed the settings, but when I deselected the effect in Inspector (clicked on the little blue box) to ignore the settings then changed the effect... all the settings changed back to their default values (except for the 'Quantity' slider). This isn't how it's working. Deselection of effect should work as a derivation not a reset. If someone else can confirm this?

    This happens even to the VOE effect when saving file > save Audio effects presets, inserted on clip, unchecked then reselected in the Inspector.

    The shortcuts are for tools to the left and to the right of the top of the keyboard that you see here. The iPhone screen is probably too small to make use of this feature.

  • How can I change the network settings and air play setting up the itunes which is running on my laptop (windows 10)
