Which stream formats do you prefer?
« on: 14:14, 18 March 20 »
As we can stream in various formats and quality levels i'd like to ask, which stream format and quality you'd like to have to listen to roland radio. We can provide MP3, Ogg Vorbis, Opus and FLAC.

MP3 is fine to me... I don't know what it the most efficient (in term of compression ration and decompression CPU resources... Yes, my ecological conscience is speaking :))

It would be great to stream to the CPC directly using the M4 card. The best format in this case would probably be the AY format. We already have telnet and irc, so this should be doable using too.

Hi Gunhead.

As you surely know AY/YM is not a streaming format.
I have already mentioned the available and possible formats above. These are MP3, OGG, OPUS, FLAC.
To deliver AY/YM directly our broadcasting software is not suitable; and the CPC probably isn't either.

But if you can develop something in this direction, I would be happy to hear about it. We will offer the AY/YM-files (as far as we have them) for download for each title.

Regards,
RolandRadio

Nice, the CPC would need to download the complete song first then play it. But this should not be a problem, because it's only KBs instead of MBs. So actually you could stream AY/YM and MP3 in the same stream.

Hi Gunhead....

It is impossible to handle a combination of different file formats in the same stream via the streaming server. This is not a TV format where you can use screen lines outside the visible area for data transfer.

What we are doing right now is to provide the artist and the title as streaming information. This information should be readable even by the CPC from the header of the Icecast stream. We could then provide the appropriate AY/YM file on our server.


The CPC then parses the title from the stream and loads the corresponding YM file of the same name from the server.
In my opinion this would be a feasible way.


As soon as you make this possibility available on the CPC, we will set up and provide the necessary functions on RolandRadio.

Well, MP3 files have documentation part. Thought it would be possible to integrate the short AY/YM parts there. But your way is also a nice one. On CPC side we got the M4 card and also the SF3 to access the internet. An application can be done for SymbOS, it already has the environment for that.

Those extra mp3 informations you can save within an mp3 file are not transmitted within an icecast stream. So parsing and fetching will be the only option. As i am a total noob with the cpc itself i am not able to code an application under SymbOS to do the job. This should be a task for an experienced programmer as you are.

Mmmh... It *is* possible to stream YM, I did that with Arkos Tracker 2 with a serial interface like Albireo/USIfAC. But all the music was recorded in WAV! Don't expect me to record all these songs again :). Plus, YM is a crappy format which may not reproduce all the music "features", shall we say (some players are really strangely done, producing some strange artefacts, which we are used to).

And seriously, who will bother turning both his PC and CPC, a streaming radio, the whole setup just to listen on a crappy buzzer, or even on a speaker?

I planned a long time ago to build a nice little streaming radio based on some raspberry or other integrated chipset. I have molded a nice Roland where i can put in a bigger mono speaker, a line-out and the needed board. but i am unable to code the streaming client for the board. So maybe someone has the electronic abilities to do this? Maybe Toto?

Most of the time, people with electronic abilities are not the ones with software development capabilities! I don't think Toto code (I saw him many times, never saw him in front of an assembler!).

About the quality, I think 128+64k stereo+mono would be enough.

On CPC, I mainly do hardware and graphics. I dislike to code for hobby stuff as it was my main job during years.

Thanks for the flowers, but I'm not. However there are some experienced coders (for example from the Netherlands) who are great in such things. The already did Email and IIRC. Maybe they like to help. We'll see.

I would prefer to use my CPC with the same "crappy" speaker you're using at your PC.
Why? This way I save the space to have some additional PC staying around just to play music.  :)

But would you be able to design a board for building a hardware Roland radio? Or do you know someone who can do this?

Sadly no, I have currently some projects to finish for the next 2 years. I don't know peoples doing that.

By the way, don't get me wrong, I *love* the CPC speaker and only swear by it when playing on CPC :). But I admit the CPC radio offers a nice sound, probably less tiring than if the stream was played on the CPC.
