Thanks everyone for the replies.
Can you use the internal mic to record 10-20 seconds of silence (e.g. put the recorder in a drawer) in 24-bit 96k WAV and attach the file here?What input level should I use for this test to be useful? Should I max the input level?
So the data from 1983 is what we need.We?

I am also aware that on a portable device the effective bit depth of the recording will not come close to 24 bit...I think you've pretty-much answered your own question.
From what I understand, even the best ADCs don't achieve 24-bit accuracy.
The "pro standard" is 24/96, and there's no harm in using that. But, if you're making CDs (16/44.1) there's no reason for going higher than 44.1kHz.
You do loose resolution if you record leave headroom... If you record at 16-bits and your peaks only reach -6dB, you're only using 15-bits. But in reality, you are unlikely to hear any quality loss even if you go to -12dB (or lower). Don't try to "compromise"... Clipping is MUCH worse than a little loss of digital resolution!
I'll agree with half of what KozmoNaut said. It's very important to avoid clipping (Make sure your levels NEVER hit 0dB.) It's NOT so important to maximize the signal, especially at 24-bits. Pros often record at around -18dB (at 24-bits). Live sound levels are rather unpredictable and I'd start to worry if you get above -6dB.
Mic location is also very important, especially if there is an audience. Even if there isn't an audience, you'll probably want more direct sound (and less room-sound/reverb) than you hear in the usual seating position... The amount of reverb that sounds wonderful in a music hall or church, usually sounds "stupid" coming out of a pair of speakers in your living room.
Get a mic stand and whatever stand-adapter you might need, even if you have to improvise something. You may not be able to find a shock-mount for that recorder, but try to isolate it from any vibrations, and once you're recording the show, don't touch it!
Also if there's an audience, you might want to set-up a 2nd recorder to capture the applause (assuming you're not recording church services). That could be a laptop, a video recorder, or a phone, etc., and then you can mix-in the appropriate amount of applause in post-production.
And if at all possible, experiment (especially with different mic locations) by recording rehearsals and/or multiple performances. And once you've "got it right" it's a good idea to record multiple performances (if possible) because stuff does go wrong!

So... a year later, I discover the answer. Shame on me.
This time, I installed the script with no problems and it is excellent! Thanks a lot.

Record in the best quality the device can do
The OP is specifically asking about what combination is best. Are you assuming a higher sample rate is always better?
I do it with SPEK but how do I detect shelves ?

48000 is more than enough. Use 24 bits just to give head room when recording, in case you don't get gain right - but once recorded, normalize it to 16 bits.
And it's true that classical music lovers were the most enthusiastic early adopters but the main reasons mentioned at the time were a lower noise floor and the ability to play a complete work without having to turn over rather than sound quality itself (though you might consider lower noise a quality improvement). Having said that I'm sure there were many lured by the promised improvements in sound qualityLets see it.
Thanks. However, I was talking about early adopters. So the data from 1983 is what we need. I was also talking about the UK market which may have handled the launch differently

Record in the best quality the device can do, provided you have enough space. Make sure the input level gain is correct so you maximize the signal level without clipping. You can always downsample and reduce bit depth later.
