Re: how to use sound files in C# ? - C# Discussion Boards

11-Jan-06 8:54

if I have some sound Files , and I want to play them one after the other , the performance of hearing them not good because the time to call each one . So, I try to use a MemoryStream to make the sound files become a single group so, I will need only one call , but I failed to make it .
Then I used FileStream to create a sound file and I called it "sound.WAV" , and by using for loop append the sound files in "sound.WAV" , but only the first file appended
...............
I hope you to help me ... here my code after seeing your site .. Really it is a good site ...

public int SND_MEMORY = 0x0004; // pszSound points to a memory file
public int SND_LOOP = 0x0008; // loop the sound until next sndPlaySound
public int SND_NOSTOP = 0x0010; // don't stop any currently playing sound

public int SND_NOWAIT = 0x00002000; // don't wait if the driver is busy
public int SND_ALIAS = 0x00010000; // name is a registry alias
public int SND_ALIAS_ID = 0x00110000; // alias is a predefined ID

With .NET framework 2.0, you can use System.Media.SoundPlayer to play wav sounds:

System.Media.SoundPlayer player = new System.Media.SoundPlayer();
player.SoundLocation = "c:\windows\media\ding.wav";
player.Play();

If you need to play wav, mp3, and WMA, you might want to look into Managed DirectX's AudioVideoPlayback class.

I can play the sounds by the functions in class WAVSound that I have mentioned in my message , but I need to make the sound files be played with a few time between them or playing them as a single sound file , and for this reason I think to append them in one sound file
please try to see my code in the first message and tell me how could I make this idea , or if you have another idea please explain it .
I think I can decrease the time between calling sound files by storing the sounds it self ( not their paths ) in an array , so, all of them in RAM after that using loop to playing them so at play loop no time to call sounds from hard disk .
but the problem is how can I make an array that store sound files it self not names of sound files ??
thanks a lot ....
I will send my code in your E_maile ... really I can't thanking you ...

If you're not using 2.0, you can go to www.pinvoke.net and get the code to use the PlaySound API.

How can I appened sounds if the sound file has a Canonical form , how can I program it ...
thank you .....

What do you mean ? You want to merge files ?

That's cool, I don't speak any other languages at all Smile | :)

I'm not sure how you'd go about joining two wav files, I'd guess you need to know the file format, and then parse them, and write them out manually.

My program is Text To Speech In my language,
for example, if I have sound for litter 'H' And sound for 'e' and the same thing for 'l' ,'o' and 'w'...
to hear the word "Hellow" I should play each sound , so the performance will be good ( like human speech not machine ) if I merge the litters sounds in one sound file
but to merge them I should change the canonical format of the file , how can I program this ? ...

First of all, the end result is plain not going to work, unless your language is very different to English.

Secondly, you will need to read the files as a byte stream, then examine them, and create a new file that is of the correct format. Which means you need to learn about the wav file format. It's uncompressed, so it can't be too hard.

Why don't you create mp3s of all the sounds, turn them into a playlist for each word, and use the Windows Media Player control ?

this is my code and it depends on a class that analysis the word in my langauge ,the first sound can be stored in "sound" , how can I change the format of the new file "sound.wav" to append the other sounds ?
excuse me what is the advantage of mp3 rather than wav ?
//-------

FileStream fsr;
FileStream fsw;
byte[] SoundBuffer = new byte[Max*Max];
//----------------------------------------

fsw = new FileStream("sound.WAV", FileMode.Create);
fsw.Close();
int i;
for(i=0;i

Please don't keep asking the same question over and over. The answer remains - you need to read up on the wav file format, and then put apart your data accordingly.

1. The initial files are smaller
2. WMP will almost certainly play your files just as quickly as your joined together wav solution ( will probably do the same for wav files, actually ), without the sort of code you're trying to write at the moment.
