Recording Audio / sample rates

[Lejardin]

I've been trying to record some guitar into Luna3 along with some midi tracks.

When using the AISO Direct X Full Duplex driver of my aged Audigy to capture the guitar I get a message telling me that the recording is too low (-57 db I think it said).

I CAN record using the Creative EMU10Kx AISO and it sounds fine if I'm just playing along but it sounds awful - really discordant when recording (no its NOT my guitar playing!).

My Audio Setup lists another AISO driver but LUNA crashes if I select this.

Is this something to do with the sample rate - does playing back the midi stuff that was initially done at the lower samplerate transpose it at all? I can understand the audio recordings changing but does it affect the midi too? If so, iss there a way to rectify this? Maybe by transposing the midi to suit the new audio sample rate (how much by?)

I'm using a 1G Athlon with 384MB RAM and Windows XP

Thanks

Try lowering the audio recording threshold:

[Lejardin]

Thanks - It sort of works!

I no longer get the message about the recording level being too low, and I can see that something has recorded but all I get on playback is white noise.

Everything is perfect with the creative AISO driver, except the difference in pitch affecting the existing midi stuff.

The simple thing is to stick with the drivers that are ok and redo the midi bits I guess. If I was clever enough I'd work out how much to transpose them by!

[Drenholm]

I don't think that transposing is necessarily what you need to do - but neither do I know the solution. I think you should wait for someone more educated (e.g. Jo) to come along before doing anything drastic!

It would help to have a more complete description of the signal path. For example, if the guitar is plugged straight into the Audigy, then the signal level is probably too low and the impedance too mismatched to ever make it work. So, a few more details pleae, Lejardin.

Good point DaveL

My guitar is amplified before it reaches the soundcard by running it through my effects unit and out through the headphone socket. I then run this through my old 4 track so that I've got some fine control over the volume level and to give me an accessible jack for the guitar leads - This then goes to the mic input on the soundcard.

Using this setup and the the creative AISO drivers in LUNA gives a perfect level and I have recorded in other software like this with the AISO DirectX driver without problems (but haven't tried recently now that I think about it so it might not be a LUNA issue).

it's probably a soundcard / driver issue; I'm quite happy just switching to the Creative drivers. I just wondered if there was an easy way to keep the midi stuff that I'd already done.

Please, it's ASIO.

I'm with you to here.

and to give me an accessible jack for the guitar leads

But you lost me here. Accessible input jack? If so, is this straight from the guitar, and does the 4-track have a suitable instrument input? And why aren't the guitar leads also coming through the effects unit?

This then goes to the mic input on the soundcard.

It seems to me that this ought to go to a line-level input on the soundcard rather than a mic level input; otherwise I'd expect you'd get substantial clipping at the soundcard mic input (i.e, it would sound really crappy and distorted). I'm assuing that the effects unit output is probably stereo, so why wouldn't you use a stereo line-out from the 4-track to a line-in on the soundcard? What output of the 4-track are you using here?

I just wondered if there was an easy way to keep the midi stuff that I'd already done.

I might need to re-read the original post, but I though this was about audio levels, not MIDI?!

ASIO - Sorry!

4 track just saves me crawling round the back of the computer to get to the inputs and I can't leave it all connected as the children are too inquisitive. The leads come out of the effects into 4 track and then into soundcard. Its a guitar effects box that gives me the amplification I need. Its only a mono output.

I just went to change the input from mic to line as suggested it but the the line in control on the recording properties has vanished! The mic delivers reasonable sound though.

The thread was / is about audio levels but I don't want to waste the work that i've done. Either I solve the audio or just start again with the ASIO (thankyou ) driver and redo all the midi.
