Title: Anyone *EVER* used ahi.device for recording?
Post by: bubblebobble on December 23, 2009, 08:04:43 PM

Has anyone *EVER* used ahi.device for recording?

I ask this because it seems to be broken, it has drop outs.
At least under my WinUAE installation using my code. But the library interface works.
So I guess it is not the uaeaudio driver.

It is either the ahi.device or my code, however, I tried everything and read the recording example from the ahidev.lha approx. 1000x.

Is there a program out there that uses the ahi.device for recording so that I can test, if this is my code or indeed the ahi.device?
(and ehm, no, AHIRecord uses the Library interface, and Samplemanager uses my (buggy?) code)

Maybe soundfx uses it.

Maybe Audio Evolution does:

AHIRecord seems to work fine on OS4 at least.

As I said, AHIRecord uses the Library Interface.

So do AudioEvolution and SoundFX.

HDRec I believe does.

HD-Rec uses the Library interface too. I am the author, btw. ;)

The Library Interface works fine.

Just the Device interface is dropping some audio, which results in missing audio fracments and crackling, very anoying. I checked the sourcecode of AHI, and the device interface usess the library interface to fill the buffers, so I am pretty sure now that this must be a bug in ahi.device code. Is Martin Blom still active? Any other developers of AHI around here?
Anyway, the example for device recoring in ahidev.lha looks strange to me and ill-designed.
First, you fill a buffer with DoIO() and then call subsequent SendIO(). There is no real double buffering, there is always a small gap between receiving a buffer and sending the next one. So AHI must store audio for an undefined time, since it does not know how long it will take me after I got the last Request till I can send the next one.

Many moons ago I used "speak freely". You can do a loopback test fairly easily. I used it with a GVP DSS8+ parallel recording device on an A1200
