What's a good API for recording/capturing and playing back sound in Delphi and/or C#?

<flavor> I want to create a spelling test program for my grade schoolers that would let them enter and record their spelling words then test them on them through out the week.</flavor>

What's a good Delphi API with which I could select a recording device, capture and save sound files, then play them back?

I'm also toying with doing the same project in C#, so C# Sound capture/playback API recommendations would also be appreciated.

The best place to look for Delphi Components

I've found New Audio Components to be quite good for Delphi.

An alternative to recording would be to use the MS Speech API with C#, enter the words via keyboard, and have it state what was keyed in.

Just a thought... Good luck on your app -- it sounds like a really cool program!

I'll play with that, my concern is that it probably will mangle a few of the words via phonetic pronounciation. (i.e. 'though') and confuse my kids more than help them. If it works though it'd be slick.

It works pretty well actually, and it is possible to spell them in different spellings to 'encourage' the engine to pronounce them properly.

Yeah, I'm definitely familiar with that (forcing phoenetic spellings) - 'wich is wie I woud nott want et en eh sppeleng drel' :)

Even the speech synthesiser I had on my Apple IIe didn't need that much help :DBesides, who says you have to display/expect the same string as what you're sending to the synthesiser?

This component set looks promising though I've never used it myself. AudioLab 3.1 has both VCL components as well .NET 2.0 components which should allow you to use it whether you stay with developing your application in Delphi or move to C#. Finally, it appears to be Free for non-commercial use.

Why not use the TMediaPlayer that comes with Delphi (in the System Tab of the Palette)?
It can record and play wave files very easily

I was also going to suggest AudioLab.
