MP3 Files and FLDigi

A quote from https://www.theregister.co.uk/2017/05/16/mp3_dies_nobody_noticed/

==========================================================================================================

MP3 'died' and nobody noticed: Key patents expire on golden oldie tech

And Fraunhofer won't renew 'em

Key patents held on the MP3 audio format expired last month – and it's taken three weeks for anyone to notice.

And the Fraunhofer Institute has declined to renew the intellectual property it owns on the MPEG Audio Layer III technology – as well as terminating its licensing programme. So yup, now you can use MP3 encoding in your products almost patent free – others who worked to develop the format still hold some of the patents – and, of course, your MP3s that used to work will still work in the future.

==========================================================================================================

So legally, the mp3 codec could be added to fldigi.  But there are better public domain audio compression codecs, notably ogg which provides a better quality audio / compression than mp3.

I will consider your request.

If it's possible, I want to transmit an mp3 audio file. I know FLDigi will do .WAV files but can't figure out how to do mp3...

Al,

I'm still a little confused.

Do you wish to transmit an MP3 file, such as a song, to someone
so that they can play the mp3 file and listen to the song?

Or, do you wish to create an audio stream of the FLDigi output and
then play that stream back and have FLDigi transmit it? 

FLDigi can PLay back WAV files.  MP3 can be converted to WAV for
playback.

But playing back a file and having FLDigi transmit it is more difficult.

In the past I have used AudioPaint program to create large text in the waterfall.
The program generates a Wav.  The only way I could send it was to have a
program play it back and route the audio to the SignalLink.  The VOX on the
Signallink would then key the radio.  I haven't found a direct way to do it directly
within FLDigi.  Note - this was done on a repeater, so bandwidth was not a problem.
I was checking in to a local Digital Education Net.
Following is example of what would be received:






I agree.  It would be great to have a Macro command that would xmit a WAV or MP3 of FLDigi audio.
That way you could pre-record bulletins and send then out.  I know that this can be
done just using a text file.  But it might open up some other uses.

Re: RFi help and Raspberry Pi

Here is an opportunity to use a Raspberry Pi as a headless computer.   That is, no monitor or keyboard attached.  Use your existing computer to control the RPi.  Already having a Signallink connected to your radio already is a definite advantage.

You will need a RPi (3B or 3B+), a  power supply and a 32 Gbyte microSD card.   Probably a case also.

If you Google "Raspberry Pi Headless" you will get many hits.  Here's one that is pretty good:
https://www.tomshardware.com/reviews/raspberry-pi-headless-setup-how-to,6028.html

I suggest you find someone in your local community that is familiar with the RPi to help you set it up.

I’ve been a longtime user of the FLDigi suite of programs.

Mostly use it with a windows computer.

 

But I have several Raspberry PI’s set up with the FLDigi suite.

They work great with one small quirk.

 

I’ve noticed that sometime during a Mode Switch (Ie, from MSK32 to BPSK125),

there is a pause of about 15 seconds and then the program continues.

This can occur when sending or when receiving.

It does NOT occur every time and it also does NOT always occur on the

same mode switch.  So I can’t make it repeat.

 

When it happens on send, you try to send, system pauses for 15 seconds,

no transmit during the pause, then the mode switches and program

transmits the message.

 

When it happens on receive, you receive the mode switch ID, system

pauses for 15 seconds, and then continues to operate normally.  Of course

by that time you have missed the first part of the message and quite often the

entire message.

 

Things I have tried:

 

Recompile the latest source.

Switched from PI3 to PI3 Plus.

Lock the PI in Turbo mode.

Yesterday I re-compiled on the new PI4.

Also tried the FLDigi that is in the Buster Repository.

 

All to no avail.  Still get the pause sometimes on mode switch.

 

Question:  Am I missing something in the Compile Options –

should I be setting any special switches?

 

Is there something happening during the mode switch that

would cause FLDigi to pause.

 

Appreciate any help.

 

Thanks
