This is Hacker Public Radio Episode 4355 for Friday 11th of April 2025.
|
|
Today's show is entitled, Record Player Audio Streaming with Darkness.
|
|
It is hosted by Archer 72 and is about 10 minutes long.
|
|
It carries a clean flag.
|
|
The summary is, Archer 72 has a brief overview of streaming a vinyl record to his laptop.
|
|
Hello, this is your host, Archer 72, for Hacker Public Radio.
|
|
In this episode, this is my third show involving a record player.
|
|
I am using a Zoom H1 Essential stereo handy recorder microphone recording into
|
|
audacity for the show.
|
|
Picking up a record at the record shop expands my music choices.
|
|
I get a chance to talk to the owner on the weekend when he is searching for new music.
|
|
He is an archaeologist and a teacher at a local college during the week and is knowledgeable
|
|
on all the music in his shop.
|
|
I wanted a way to listen to the records while on my laptop, preferably with headphones
|
|
as to not disturb the household.
|
|
This is done using a combination of dark ice to capture the stream and ice cast to stream
|
|
it to a local network.
|
|
What is ice cast?
|
|
Ice cast is a streaming media audio-slash video server which is currently supports Ogbora
|
|
Cynthiaura, Opus, WebM and MP3 streams.
|
|
It can be used to create an internet radio station or a privately running jukebox and many
|
|
things in between.
|
|
It is very versatile and in that new format can be added relatively easily and supports
|
|
open standards for communication and interaction.
|
|
Ice cast is distributed under the GNU GPL version 2.
|
|
The default config file is located in user-slash-share-doc-icecast.xml.disc.gz.
|
|
If the default config gets mangled or corrupted by myself, several other types of configs
|
|
are also in user-shared-user-slash-share-slash-doc-slash-icecast.
|
|
That includes a bare bones config and the installed ice cast config is located in slash-etzy-slash-icecast2-slash-icecast.xml.
|
|
This configuration needs to be personalized by changing the location which for myself
|
|
is Cynthiana Kentucky.
|
|
I'll leave in the show notes what I changed my email address to.
|
|
The default password is hack-me, you have to change it to a more secure password.
|
|
This is located under the authentication section of the configuration file under source-password
|
|
field.
|
|
The host name also needs to be changed.
|
|
In this case it was the IP address of my Raspberry Pi 192.168.x.x is the format typically
|
|
used.
|
|
There are a handful of other fields to customize.
|
|
The first is mount point and I have it set equal to live.
|
|
This is the mount point of this stream on the ice cast server.
|
|
The next is name.
|
|
In my case it's dark ice, vinyl stream.
|
|
It's the name of the stream.
|
|
The description is this is my vinyl stream.
|
|
Next is URL and I set it to HTTP colon slash slash local host.
|
|
This is the URL related to the stream.
|
|
The genre is podcast.
|
|
You select yes or no for public to advertise the stream.
|
|
You can opt to have a local dump file which I set to recording.og.
|
|
This also records to a file as you're streaming.
|
|
Metadata is set to yes to enable metadata and that's the last of my configuration for
|
|
ice cast.
|
|
Now I'm ready to use dark ice.
|
|
What is dark ice?
|
|
Dark ice is a live audio streamer designed to record audio from an audio interface such
|
|
as a sound card and encode it and send it to a streaming server.
|
|
It supports various streaming servers including ice cast 1 and 2, shell cast and Darwin streaming
|
|
server.
|
|
Dark ice can encode audio in formats like MP3 and agborbus.
|
|
To use dark ice you can configure it with settings such as the audio input, device, sample
|
|
rate and streaming service details including the server's address, port and authentication
|
|
information.
|
|
This description of dark ice is a result of using the Brave Search LLM or large language
|
|
model.
|
|
The default config is located in slash user, slash share, slash dark, slash dark ice, slash
|
|
examples, slash dark ice.cfg.gz and is copied to the slash Etsy directory.
|
|
From there use the GUNZIP command, for example GUNZIP space dark ice dot cfg dot gz.
|
|
I use the config file from the blog by Stefan Mueller on STMLLR dot net.
|
|
This is dated August 10, 2012 as a template for my configuration.
|
|
The configuration I used in the end is dark ice dash pi dot cfg.
|
|
The audio device is configured in the input section as defined by the a record dash
|
|
lowercase L to list the capture device which in my case is the barringer UMC 202HG USB
|
|
audio interface.
|
|
In the general section the duration is set to zero which is the duration of encoding
|
|
in seconds, zero meaning forever.
|
|
The section of the config file for the audio input looks like this.
|
|
Device equals plug hw colon zero comma zero.
|
|
This refers to card zero device zero.
|
|
From here you should be able to start dark ice.
|
|
The command is dark ice and the ampersand symbol.
|
|
From here I was looking for a way to update the currently playing metadata but my coding
|
|
skills are not too good.
|
|
For this I use cloud.ai to generate code from the prompt.
|
|
In this script update metadata dot sh you may want to change the host to an IP address
|
|
of where you have the ice gas server.
|
|
The port should stay the same it's port 8000.
|
|
The mount point is whatever you pick this case the default might be slash stream.
|
|
User is admin password.
|
|
You change from hack me to the ice gas admin password and song for the moment is unknown.
|
|
The usage for this script is update dash metadata dot sh space dash s space in quotes what
|
|
you would like it to be in my case I did a test and put hpr test in quotes.
|
|
If there are any suggestions for improvements please leave feel free to leave a comment or
|
|
upload a show of your own.
|
|
I look forward to hearing about if and how other people are using a personal streaming server.
|
|
Also I'm looking forward to the show from the reserve queue dated 2024 1013 entitled Fred
