Article: THE VALUE PROPOSITION IN AUDIO: ROLLING YOUR OWN IS AS EASY AS PI Recording and working with audio files on a simple Raspberry Pi DAW


Recommended Posts

Thanks for the in-depth article @bluesman. As a podcaster who recently upgraded all my stuff, Neumann TLM 103 and Merging Anubis+, I read this with a new sense of (limited) understanding and found it very interesting. The wheels are spinning on how I can test out some of this. Very cool.

WOW😮

 

 Very impressive and informative. As I read it,  I couldn't help but notice all of the acronyms and abbreviations that many/most of us take for granted but a newbie might not. Not a criticism, just an observation... slow day at the ranch so I made a list... almost 70 of them.. I know some are so common that they are universal. ..  just something I found interesting

Thanks for the observation.  That's why I try to spell out the full terms the first time each is mentioned, adding the abbreviation to be used in parentheses, e.g. "digital audio interface (DAI)".  Perhaps I've assumed more than is justified about many of those on your list - I'll try to be more consistent with up-front definitions.

Many thanks for the recording, did you down convert it to 16/44.1?

Ignore that, I think the player I used initially down converted it. Sounds great!

Rudolph the Redbook Demo is a garden variety CD quality track.  To see what the Pi would do, I made a few recordings at 24/192, which works fine on a fan cooled Pi 4, as long as you don’t try to use loopback monitoring in real time.  But I make all of the band’s demos (for learning new tunes etc) the way I made Rudolph - it’s easy, effective, and requires no special or costly stuff.

The download you provided is 32/44.1 as per the article?

The download is Redbook (16/44.1). Each instrument was recorded separately in 32/44.1 but the final master was mixed to 16/44.1 format.
 

I recorded each of the 6 instrumental tracks as a 32 (float)/44 wav using Ardour.  I then opened them in Audacity exactly as recorded, normalized the gain on each one, applied a little DSP (eg compressed the bass a bit in the first chorus, because it’s playing the melody and I thought it needed a little punch), touched up the gains for solos, and panned the instruments to create a soundstage.  Then I mixed them down to a Redbook master.

 

This was all done on the same 4 gig Pi 4.
