Sound, merging in the tones of the Musical Instrument

Hello, I am a cool LabView student and I make a call to Sound fusion projects.

The goal of this project is to merge the sounds of music instrument 2 (or more) and get the average tones.

https://en.Wikipedia.org/wiki/Piano_key_frequencies

Lets take the example of the Piano, it has 88 keys which mean 88 tones, each tone has its own frequency.

For my project, if the user chosse tones of entry of Key88(4186.01Hz) and Key86(3729.31Hz).

then the expected tone average output should be ((4186,01 Hz + 3729,31 Hz) / 2 = 3957,66 Hz).

which means the output tone is close to Key87(3951.07Hz).

My piano sounds files are downloadable from freesound.org

https://Freesound.org/people/pinkyfinger/packs/4409

I use the 'path of file control' to play the files of tone and simple reading wire

                                       

Files (wav) sound Front panel Block diagram                                                                                                                                 

I was studying the release of simple reading, because the information tell me data is an array of waveforms, so I guess that to get the medium tone,.

Maybe I should make the way

(a) put the 2 waveforms in wavefomrs, on average, play the average wavefomrs

(b) implement table, on average 2 tables, convert to sound data and read it

Furthermore, I don't implement both ways, and I'm not sure wheter the ways are correct.

I hope that you guys can guide me, I'll very appreciate to this topic.

Not a bad bill and it will teach you something about sound waves, etc...  [Did you physics?  [You have a knowledge of music, i.e. do you play an instrument, especially the piano?]

This is an experiment to try.  Examine the middle C on the piano (about 256Hz).  Consider the C an octave above (about 512 Hz).  Play both at the same time.  What records did you hear?  If you know the music, you know that you won't hear the note 'C' (although it can be difficult to understand what octave (s)).  However, the average of 256 and 512 is 384, which is located close to a G.  Hmm, perhaps with an average of sounds is a little more complicated than the average of their frequencies...

  • Purchased ringtones are mired in the music folder and not moving to tones folder?

    I have several ringtones that I had purchased and downloaded on my old computer that I have synced my iPhone 5 and now, when I went to bring my iPhone 6 s + with my new computer Windows 10 they are stuck in the music and cannot be moved to the folder of tones to use on my phone. It was a CD MacLife and a corporate Web site that offered these ringtones. I can give the name of the company on request.

    Other tones have been downloaded of the site Web of GEICO. I can create my own ringtones, but they do not move somehow. This issue is not resolved. Clicked on something by mistake.

  • You Tube, after that 11 seconds the video stops, in all and is no sound through the speakers. No noise in the music of cd too

    For example: in You Tube, after 11 seconds the video stops, in all and is no sound through the speakers. No noise in the music of cd too.

    If you get no audio cd, youtube or anything else, you must first check in the volume control that you are using the sound card, you are connected, that nothing is on mute and volume is sufficient, or install the drivers for your sound card.

    Video YouTube can be that your internet connection is slow or too much peoole try to watch the same video, save it to your hard drive and then watch or, give him a minute or two to download in the buffer before you start watching.

  • System only through headphones - no music sounds. BUT... the music only through USB speakers. No system sounds. What is happening with this?

    I listened to the music on my computer through headphones regular plugged into the audio jack of 3.5 mm.  I could hear the computer through headphones - music, movies, YouTube, system sounds - everything.

    Then, I plugged my Microsoft Digital Sound System 80 speakers via the USB interface.  Windows XP found the speakers, loaded the right driver, gave me the message "your device is ready to use" and things started to play music that was running on the computer.  Sounds incredible.

    But now, I have a weird problem.  I can hear only the sounds system through headphones (beeps and dings that play during system events), but I can't hear the sound system on the USB speakers. AND... I can't hear the music/videos/YouTube, etc. on the speakers USB-interface, but I can't hear the sound system through the USB speakers.

    When I go to the audio tab of the sounds applet in the control panel and change the device for audio playback by default "SoundMAX HD Audio" to "Microsoft Digital Sound System", then I hear everything - system and all - sounds on USB speakers.  But then I hear anything through the headphones.

    I want to be able to Exchange music back to making the USB speakers.  How this is done?

    Yes, they are older speakers.  But they work a lot.  And the digital sound via the USB interface is excellent.

    Hi BitSpanker,

    The only option is to change the audio device by default for the device that you want to hear the audio.

    (a) click Start, click Control Panel, and then click sounds, speech, and Audio devices.

    (b) click on sounds and Audio devices, and then click the Audio tab.

    (c) in the sound playback section, under default device, make sure the audio device is the correct default audio device.

    (d) If this isn't the correct default audio device, click the drop-down list next to the device name, click the audio device you want, and then click OK.

    Change the audio device may require that restart you your computer.

  • You can save the music from itunes with the sound recorder?

    You can save the music from itunes with the sound recorder?

    The principle is simple in nature, although the tape recorder is not the best option available for you, even in free software for audio recording you can.

    If you want to use sound recorder, you will need to get a 1/8 inch male-male stero (cable basically a helmet with two male ends) and put one of your speakers into your microphone in the port (line in).

    Then open sound recorder and give it a shot. The recorded files will be in .wav format, so you need to get a freeware to convert to program them to .mp3 if necessary. Or use this:

    http://www.media-convert.com/

    You can also use Windows Media Encoder 9, which in my opinion is much better in features and maintaining the quality. It is freely accessible to the public.

    http://www.Microsoft.com/downloads/details.aspx?FamilyID=5691ba02-e496-465a-bba9-b2f1182cdf24&displaylang=en

    You use the same configuration that with tape recorder, get a stereo cable and speaker output connection > microphone.

    Method 1:

    Sometimes a Web site you visit doesn't look like you expect it. Images may not appear, menus may be out of place, and text boxes may be blurred together. This can be caused by a compatibility problem between Internet Explorer and the site that you are. When a site is not compatible with Internet Explorer, you'll see the compatibility view button in the address bar. You can activate only display Internet Explorer compatibility for the office.

    Use compatibility mode in Internet Explorer:

    Method 2:

    I would say to change the mode of Internet Explorer 9 browser.

    Steps to follow:

    a. open Internet Explorer, press the F12 function key.

    (b) in the part of developers, click browser mode and click on Internet Explorer 9.

    If the Web site uses flash player, try to uninstall and reinstall and check if it helps.

  • Monopoly Tycoon - why I can't play with the music?

    Hello everyone,

    The game, Monopoly Tycoon, seems to have a problem where it will crash on Windows Vista and more if the game goes to play music. If the music is turned off, the game will run very well.

    The thing is, I would like to have the music of the game. The music is meant to be the 'tone' of the present age that you play in, and take it again lost of nostalgia to start.

    It looks like it should be a really simple solution - sounds work very well, but music (WMA format), will crash the game for some reason any. I can play the music in windows media player very well, said by the way.

    Can anyone suggest a solution that doesn't involve turning off the music or play any music loop in the background with a media player?

    Thank you!

    So here's how I did this work under my 8.1 Windows Installer.

    1. install the free vmware player.

    2. install Windows xp in a virtual macine on ure computer current 40 gig is good

    3 install the software to mount the .bin file and install the game

    4 fun playing the game by using the windows xp vmware player full screen.

    even the sound and music work like a charm, and you can return to your windows desktop 7 or 8.1 in a few seconds.

  • Are the musical atmospheres to Audition CS5.5 really limited?

    Hello!  Here are some facts: I'm a pretty big user of After Effects and Illustrator for making animation tutorials... and a big fan of the Master Collection in general.  I write and tell scripts for the tutorials, adding short video clips and sound effects.  I have a laptop of MacbookPro with Snow Leopard. Reluctantly, I spent the money for CS5 upgrade to 5.5.  I had just learned a lot about Soundbooth and was happy with it, but I learn hearing.  I recognize also that the audio is more than a world of PC and the side hearing Mac "seems", in some respects, to be the child of the hearing step for now (I'll still have to hold down the SHIFT key when I starts the program if I want to save).  OK, I know that I am a newbie with hearing and that I am not asking to much compared to what it is oriented, so maybe I'm also completely missing out on some aspects of the central resource hearing which are at the heart of the questions that follow.  If so, just put me straight... pleeease:

    1] Soundbooth "music"beds" were musical pieces with a length to them and several sections to them, and they sounded like real songs and clips not quicky.  Hearing has a few quickies and that's it.  Is that really all?

    [2] the loops are also very limited.  Is that all there is?

    [3] there are tons of sound effects, but many are a shade of the same sound after another.  While I am glad that all of this is available, but I wonder, for example, why (and perhaps I just missed) there are many marked sound effects 'Crowd' that are so specific that they are generally is not useful, but it seems to be no cap of background noise as there will be a casino, or the theater or auditorium.  I'd trade in some of the techno sounds without end for a clip of corn popping.

    4 If the answers to questions 1 to 3 above are not something like "do x, y and z and you will find what you are looking for in the Resource Center," then why the aspects of this feature were stripped down.  Given the cost of the upgrade from 5.0 to 5.5 and giiven who with a few decent royalty free in my arsenal is very useful when I use very little music, this apparent retirement seems to pay more for less.

    [5] Finally, where power users go for you, audio clips (free and fees)?

    Thanks in advance to all! You are the best!

    Quill Road

    Thanks Steve, I seem to have the music of the beds, which still seem very limited, already by the central resource, but certainly did not know that I had access to all of these loops.  It seems that there are a few skills to put together, but I'll try that.

  • The music stops when messaging on viber

    so until I have updated to iOS 10, I can listen to my music and message on viber.

    somehow after the update to iOS 10 whenever I try to post on viber while listening to music, the music stops playing. And when I slide up to listen to the music it shows this. PS I upgraded viber last night their last 10 updated ios as well.

    I tried turning off the sounds in viber notifications, but that didn't work either.

    Just turn off "Sounds In - App" "Notifications" on your Viber settings.

  • No sound when connecting the Macbook Pro to ext speakers.

    I have a MacBook Pro (retina, 15 ", mid-2014) running OSx 10.11.6 (El Capitan).

    It has a combined audio port 1/8 "for two speakers and a microphone. The internal speakers work very well and the port works very well with a helmet. What does not work must connect external powered speakers like the computer speakers or the port on a radio. It worked perfectly with all other computers that I have ever owned, and judging from the page linked below it should work for this computer, too, so what's the problem?

    Connect your Mac to a Hi-Fi, iPod, iPad, musical instruments or loudspeakers - Apple Support

    I tried it with a 1/8 "cable this single sound of the door (no tape for micro), and (when it does work), I tried to first insert an adapter that split the audio and microphone, but it does not solve the problem.

    How to make this work?

    I found the problem. When I plugged a cable into the headphone jack, the Mac automatically turned to the low volume - assuming I have connect headset. This is why I couldn't hear it. I open the sound applet in the system area and pushed back the volume of output to the top and voila - fixed.

  • From itunes to an mp3 CD burned on a macbook OSX 10.7.5. The cd plays a sound skreechy in the wave cd player. How can I fix it?

    Burned a cd from itunes to an mp3 on a macbook OSX 10.7.5. The cd plays a sound skreechy in the wave cd player. How can I fix it? The cd will play the mp3 in the macbook. He play the cd or access my itunes music? I burn on CD documents successfully. But I've never burned audio successfully. Please notify. Thank you.

    For problems of audio on a CD (as opposed to combustion problems do not at all), you can often clear up by re-burning at a lower speed.  Use 2 x.  This setting is available in the dialog box burn the disc.

    All the new iPad will run iOS 9 now. It would take a 16 GB iPad. I have 425 songs on my iPad, and they represent 1.8 GB of storage. But... You cannot add storage to an iPad, then you may want to consider eating less up to 32 GB. You never know what you could want on the road.
