Jul 21, 2011I'm creating an application that will have 3 streams of audio. I can get 2 streams playing easy enough using DirectX AudioVideoPlayback and setting the balance for each Audio Instance. However, I need a 3rd Audio instance to play out of another output such as the Rear or Centre. An alternative would be to be able to select a different sound device in the machine to play the 3rd audio stream.

I've tried a few alternative libs such as DirectShow.Net, DirectSound, BASS.Net, QuickTime and OpenTK.Some of them do what I need to do, but they are either too difficult to use and therefore impractical or they are missing some other essential features such as Events which are required to make the rest of the application work. Would anyone oppose to me posting this same thread on other forums?I will of course post a solution if one is found elsewhere without advertising external websites.

Direction For Sound Through Sound Card?
May 27, 2011Is there a way to generate a pure tone (e.g. 440 Hz) for a specified period of time through the sound card without using having to find or make a separate .wav file for each tone.I tried using the "Beep" function, but while it produces the tone for a specified period, it sounds broken up into a (probably 500ms) time frame which repeats with an audible space between the repetitions.

View 3 RepliesFrequency And Duration Through The PC's Speakers?
Jan 1, 2011A simple class that plays a tone of varying ampliture, frequency and duration through the PC's speakers:
Imports System.IO
Imports System.Media
Public Class Form1
Private Sub Button1_Click(ByVal sender As Object, ByVal e As EventArgs) Handles Button1.Click
Beep.Beep(1000, 1000, 1000)

This class uses SoundPlayer.PlaySync which has a 4 MB stream length limit, so the longest duration is 24000 milliseconds. You can try SoundPlayer.Play for longer durations, but allow plenty of time for it to complete.
Detect The Frequency Of Audio Coming?
Mar 25, 2009I am looking to be able to do life frequency detection in VB.net. I must say I don't really know where to begin here. I have looked into BASS.net, but that seems to only work with pre-recorded audio. I need to be able to detect the frequency of audio coming in over the line in or mic input in near real-time.
View 2 RepliesDetermine Key Points In Change In Frequency?
Sep 29, 2011I have an application in which I am analyzing a system where there are a large number of interactions. And I need to make certain choices based on the frequency of the occurrences of unique items in the system. For example, if you had this list of letters:A, B, F, G, A, T, S, B, S, B, S, Q, Z, B, Q, S..[code]The above is a tiny example, but I've attached an image which is a simple line graph of a larger system..In this graph the numbers along the bottom aren't really important. They are just marking the number of unique frequencies. And the Y-axis marks the value of that frequency. What I'm looking for is a mathematical/programmatic way to find the point where that line begins to break upwards. My searches haven't yielded what I'm looking for as I'm not really sure what the proper terminology is, or the name of the concept.Right now, we have to manually choose that point based on a human looking at the numbers and saying "here". But I want to, at the very least, already have a "recommended" value chosen, and at the most, be able to remove the human component completely.
For clarification, my current algorithm is producing a list of number pairs occurrence to occurrence frequency. My use of the word "frequency" in no way relates to electromagnetic signals, but rather to how often an occurrence occurs. But I thought that saying "occurrence occurrences" would be more confusing! In this system, the general trend is that a few entities will show up in a large number of interactions, more entities will show up in a medium number of interactions, but the greatest number of entities will show up in just a few, or even no, interactions. It would be tough to imagine a scenario where it was different than that... worst case would probably be a plateau. But there could definitely be a dip after a jump at any point from the beginning to the end. The illustration above just doesn't show that. We cannot assume that there will be a point where it will begin to rise with no drops afterwards.Ultimately what I'm trying to determine is the importance of an entity based on how often it occurs in the system. I need to be able to flag certain items as "important", but all items can't be important. And the method/algorithm I'm looking for would help to identify at what point in that list do I stop considering items important. If you look at the list, you can see where the lower occurrences start becoming more frequent. I don't think that I can sort on the right column because the left column is really the key data. Greater occurrences = more importance.

Then I am to call a function that will count the frequency of A,B,C,D,E . Then it is supposed to send the information to a listbox. Eg. There are 2 A's,There are 0 B's, There are 5 C's..
I have the code for populating the array, but when it comes to searching it for the frequencies..This is what i have so far..

C# - Counting The Frequency Of Specific Words In Text File?
Dec 23, 2010I have a text file stored as a string variable. The text file is processed so that it only contains lowercase words and spaces. Now, say I have a static dictionary, which is just a list of specific words, and I want to count, from within the text file, the frequency of each word in the dictionary. For example:
Text file:
i love love vb development although i m a total newbie
Dictionary:
love, development, fire, stone
The output I'd like to see is something like the following, listing both the dictionary word and its count. If it makes coding simpler, it can also only list the dictionary word that appeared in the text.
WORD, COUNT
love, 2
development, 1
fire, 0
stone, 0
Using a regex (eg "w+") I can get all the word matches, but I have no clue how to get the counts that are also in the dictionary, so I'm stuck. Efficiency is crucial here since the dictionary is quite large (~100,000 words) and the text files are not small either (~200kb each).
Copying Elements From List Where Frequency Is Custom Class
Sep 21, 2010I'm trying to copy the elements from a List(Of Frequency) where Frequency is a custom class I have made. Everything in the other places seems alright but the problem seems to be with the copying, where it still references the original table, so changing the values of one changes the original. I've tried the List.CopyTo() method and tried converting to and array with List.ToArray and then using Array.Copy but it seems they always change the original. I've also tried a for loop and create and New instance of the classes but that doesn't work either. What I'm using it for is to pass the List(Of Frequency) to a new Task to do multitasking(), if anyone can think of a better method to pass a List(Of Frequency), or an array to to a task and have it not change the original.
View 3 RepliesCreate A Form With A TrackBar Control : Generate A Frequency?
Feb 17, 2010create a form with a TrackBar control so that when you Scroll the TrackBar it generates a frequency based on the value of the TrackBar. Beep() isn't really what I'm after. I was wanting it to smoothly transition through the frequencies. Basically, I want to create something that sounds something like a Theremin.
I've been looking online, and I can't seem to find anything. I don't even know how this would be accomplished. Is there a simple command to say "play this frequency until I tell you otherwise", or do I need to generate a .wav on the fly and have the system play that?

View 4 RepliesLooking For Strange Algorithm For Frequency Rate Appearance Of An Object?
Oct 7, 2010I've been racking my brain lately to try and come up with an algorithm to set a frequency rate at which an object may appear.
This best way I can think to describe a "for instance" is gonna sound nerdy but here goes.
Say I have a subclass that is just one of many on a Large class, kinda like spades in a deck of cards. However I dont specifically want 13 spades in my deck, I want to randomly generate this deck with a random chance of spade appearances. but beyond that, i want to give each sub-subclass, like a jack of spades, a "Frequency number", that upon generation of this main class (or deck in this example) will use random in combination with this "frequency rating" (0-100) to place the sub-sub class and even the sub classes in place.So as for my example, a 2 of spades might have a high freq like 90 and thus showed up 15 times in my deck, while the jack, with a rate of say 20, only showed up once or twice in my deck.
