I'm assuming that your vocalist is being accompanied live (otherwise the problem disappears by using a second pass) and is being accompanied by said piano. So both PCs' recordings will have piano on them. How do you mix than so that the phase of the piano signals is preserved? It's not clear to me (but might be worth an experiment) that you could avoid phasing effects or localisation (precedence effect) instability. However, if it works, so be it. Give it a try. Perhaps you can synchronise the recordings by minimising these very effects. Cheers, David.

That was me, and we had moved on to multiple PCs, whereas now we're back to talking about one PC with multiple channels. Back to two PCs, it did occur to me that if you mix your L/R from the piano onto one channel of the final mix and use the singer's mic in the other, you might get fewer artificial effects, particularly with speakers because the room contributes plenty of muddling. Way back in 1958, the BBC tried experimenting with stereo broadcasts on Saturday mornings using TV for one channel and the Third Programme (radio) for the other. Naturally there was a lot of strolling around the studio at their end and fighting over the hot seat at our end. But without any other experience of stereo sound (in the true "solid" sense of the word), it's difficult for me to recall how well the effect was transferred to our living room. Nor do I know how similar the signal processing timing was between a cheap, inherited, Band I TV and a state of the art Leak Trough-Line Band II tuner. With TV chassis floating at mains potential, there was not much thought of mixing the channels or tape recording them. Cheers, David.

Well, no, I tought of: left channel on piano bass, right channel onto piano high notes and voice, say, somewhere in the middle... > Way back in 1958, the BBC tried experimenting with stereo broadcasts > on Saturday mornings using TV for one channel and the Third Programme > (radio) for the other.

But now I got very interested in the multi channel audio interface you suggest... Before looking for one to buy, I'd like to better know and understand how it works... For example in the case of piano (two mono mics) and voice (1 mic, say mono as well)... Cheers, Rodolfo

They're just boxes which can have more than two mics (or line-level signals eg from instruments) plugged into them. Inside there's multiple analogue- to-digital converters. The digital data from all of these is then sent along the USB connection to the computer. Some interfaces might send all the channels so they arrive in a single file on the computer, which then contains multiple separate channels, others may directly generate separate files on the computer. It's unimportant which you get because a file containing multiple channels can be split into separate files (with eg sox), or a set of files can be combined (with eg sox).

Here: https://stackoverflow.com/questions/14950823/sox-exe-mixing-mono-vocals-with-stereo-music it is shown how to operate with sox the way you said. > There will be lower-spec interfaces around too, but you obviously need to > find one that's known to work with linux.

That is called a stereo break-out cable:

As I understand it, professional digital audio recording gear includes
clock in and clock out connectors. All the devices are linked together
with cables, one device serves as the master clock, and all the other
devices are slaves.
Without hardware clock synchronization, the clocks for the various
recording devices will drift ("clock skew") and the recordings will lose
time alignment. One work-around is to record audible synchronizing
marks near the beginning of a take and near the end -- e.g. strike two
sticks together, clap your hands, use a "clicker" device, etc.. Then
during editing/ mix-down, use digital audio workstation software with
time-stretch/ time-compression/ time-alignment features to adjust the
individual recordings until all the synchronizing marks line up exactly.

It seems that Audacity can do that...

The single best reason for using a multi-channel (ie not just a stereo) audio interface is simplicity. All the channels will be in-sync with each other and all the audio signals can be captured on a single computer. -- Jeremy Nicoll - my opinions are my own.

For human voice, I bought a USB audio card and plugged a third microphone into it. So now I have: mic1 for piano basses; |__________ plugged together into the mic2 for piano highs; | above Y cable mic3 for voice -> -> -> -> plugged into the USB dongle. Then I do: $ sox -t alsa default piano.wav and, at the same time, on another xterm session, $ sox -t alsa wh:2,0 voice.wav where wh:2,0 is the USB device (do: `arecord -l' first). This way I get two audio files: piano.wav and voice.wav. The first one is stereo and the second is mono. In the end I merge the two together with Audacity. By default, Audacity puts the mono file just in the middle between left and right channel; but, if you like, you can have it weight more left or more right, in the percentage you want. I must say that the result is acceptable, and more... Thanks, Rodolfo

But can we say that all this allows us to do without mixer or multi-channel audio interface...? In fact, I suppose I could even add some other USB cards if I wanted to add more instruments, say a violin... Cheers, Rodolfo

As far as I see, Ardour and Jack are powerful tools... On the other hand, with the above recording procedure, i.e. several simultaneous sessions of sox, no drifting or latency effects did I appreciate at all... So it is maybe worth for me to continue that way till the moment such problems will arise... Rodolfo
