How to backup your vinyl records on OpenBSD2022-04-17
This article describes how to use OpenBSD tools to backup a vinyl record
For users, creating a digital backup of their beloved vinyl collection has become a second nature. Thus, there exists a number of guidelines, covering all aspects of needed hardware and software along this process (i.e. record, analyze, and repair). Where it seems obvious that we need a specially designed hardware for recording (e.g. turntable with USB), the same may not be true when we'll talk about software. Keeping the recording step as simple as possible, we'll use software that is already included in OpenBSD.

If you're interested in learning more about connecting a speakerphone to OpenBSD, feel free to read my article about that also.
What do you need?
- A computer running OpenBSD (surprise!!)
- A turntable with USB port (e.g. PLT 120x)
- A basic knowledge about the command line
I'm using a turntable
Audio-Technica AT-LP120-USB which provides an USB-interface for a direct connection to my laptop.
So starting with recording, we need to first activate it on our system by executing the following
doas sysctl kern.audio.record=1
Before we can configure
sndiod for our setup, we need to check
dmesg to get the information about the connected vinyl player.
dmesg | grep audio
In my case, the vinyl player connects to
uaudio0 and it seems to be a
BurrBrown from Texas Instruments.
uaudio0 at uhub0 port 2 configuration 1 interface 1 "BurrBrown from Texas Instruments USB AUDIO CODEC" rev 2.00/1.00 addr 2 uaudio0: class v1, full-speed, sync, channels: 2 play, 2 rec, 3 ctls audio1 at uaudio0 uhidev0 at uhub0 port 2 configuration 1 interface 3 "BurrBrown from Texas Instruments USB AUDIO CODEC" rev 2.00/1.00 addr 2 uhidev0: iclass 3/0 ucc0 at uhidev0: 3 usages, 3 keys, enum
With that information, the basic
sndiod setup is like:
doas sndiod -d -f rsnd/0 -m play -s default -F rsnd/1 -m rec -s turntable
As stated in my previous article about the speakerphone, you can use
aucat for first tests:
Basic recording with
AUDIODEVICE=snd/turntable aucat -o /tmp/test.wav
Play back using internal speaker (
AUDIODEVICE=snd/default aucat -i /tmp/test.wav
That's all for now.
