Does anybody know a command line wav player that doesn't display anything?

Valkyrie_of_valhalla · 05-15-2007, 09:07 AM

I'm searching for a command line wav player to use it with a program I'm writing (a nice little guitar tuner/ear trainer). It's supposed to run under windows/DOS ( I know, but the program is for a school project).
I want it to play a wav file, without displaying anything.

I tried mplayer, but it shows various info about the computer and the played file, even with the very quiet option. I also tried discarding the output to NUL:, which is an equivalent to Linux's /dev/null from what I get it, but it doesn't seem to work with a 16bit Pascal-written program...

Thought about modifying mplayer's source code for this, or maybe just extracting the functions related to playing wav files, but I have to go through about 2700 files and search...

So, does anyone know of such a program? Other ideas/suggestions are welcomed as well.

xmms2

What you're looking for is the playsound API. Look for the winmm.dll resources to see how to invoke in your programming language du jour.

Thank you too, I'll see what I can find out about it. It should be a good option as well, and would greatly reduce the size of the program.

Well, the LQ Rules state that I am not allowed to ask you to do my homework, and I am not asking you that. My "homework" consists in actually writing the program, which I shall do myself (actually I already wrote about 70% of it). Simply asking for an external program, for which I have previously googled and searched on sourceforge for hours, in my oppinion doesn't qualify as asking you to do my homework. If I didn't understand the rule right, then please correct me.

so if he took out ( I know, but the program is for a school project), and just left it that he needed it on windows everyone would come and help him?

Stop being a troll dasy2k1.

Unless his homework is "Find a console audio player with no display output" then his question is perfectly fine.

Ohh, Will you release it on sf?

My 2 cents -- the OP is simply asking for suggestions for an app that runs silently in CLI. Doesn't look like homework to me, given the context of the question.

Perhaps something like cdtool might be of interest, although I haven't used this personally so don't really know what it does/doesn't do.

or he can also try madplay and/or play for other things ...

//.2 cents ...

Did you try sox?

Since you're obligated to do it in Windows and your program appears to be shellexec'ing an external program with parameters (the WAV you want to play), why not do it the easy way - PlaySound.vbs.

Code:

If WScript.Arguments.Count <> 1 Then
	Wscript.Echo "Usage: CScript.exe PlaySound.vbs <inputFile>"
 	WScript.Quit 
End If 

PlaySound WScript.Arguments(0)

'-----------------------------------------------------
' Purpose:  To play a sound requested by the user.
'-----------------------------------------------------
Sub PlaySound(TheSound)

Set objWMP = CreateObject("wmplayer.ocx.7")
objWMP.url = TheSound
objWMP.Controls.play
WScript.Sleep 1000
objWMP.close
Set objWMP = nothing

end Sub

Have your program invoke:

Code:

cscript [Path]PlaySound.vbs "FullyQualifiedPathToTheWavFile"

You may want to play around with the "Sleep" time. Must be long enough to prevent the object from being destroyed before the wav finishes playing, but should be short enough so you don't have too much silence between wavs you want to play. Could mod the script to take sleep duration as another parameter.

I dunno, not elegant - but it works.

this is what i found recently ... looks like vb stuffs for me but plays monkeys audio(probably related to wave audio ?? i donno ) ...

Thank you all for your suggestions. I'll check everything out and post what worked best.

I thought about it, and also about making a Linux version. When I chose this project, it was because I could't find a good tuner on Linux for an acoustic guitar.
But I don't know if anyone would really like to use a 16 bit program written in Pascal with crappy graphics. I'll probably rewrite it in C this summer, making it somewhat better, and then post it.
