New recording option

[redblade8]

There is a such thing as HD radio ( streaming of both digital and analog waves simultaneously on  your radio ) You can currently record with either the sansa's microphone OR built in radio recorder. What about the option of being able to record with both at the same time? Though it wouldn't be HD radio really when recording, if I had a boombox with radio and it had its own radio on , recording of whats coming out of its speakers and recording with the sansa's built in radio recorder would allow for a much nicer recording.
---Also maybe an option to change what frequency you can record at? I would like to record at 44100HZ, but even 24000 would be fine...

Is FM radio really this unappreciated that no one has replied to this? Hm...anyways, can my idea work? ( Recording with the microphone & FM Radio at he same time? ) If this was implemented, under recording options and source you could pick the option 'both' instead of one or the other.

- Is it also possible to add the option to choose what frequency you are recording at? On my Sansa e280 , there is only one frequency, but I would like to record at a bit higher frequency.
Thankyou!

I doubt you can record from two sources at the same time on most devices.  That would require two ADCs.  Plus its such a strange idea that I doubt anyone else is really interested.  You're probably going to have to look into it yourself.

It depends of the model, on the e200v1 series I think it's not possible to change frequency

[redblade8]

Ah...ok I see. Why is that anyways? If I could change the frequency even to 24000Hz, I could get a nicer record.

What about the dual microphone/fm radio recording though? Is that possible?
Thanks!

Edit: It's not that strange of an idea, it's the closest I can get to HD Radio without the target having HD Radio and you can get a better sounding record from this. , no I doubt anyone would be all that interested...not many people even listen to the radio anyways anymore ( unfortunately ...)
What are ADC's ..?

Its been too long, I can't remember the details.  If you search I'm sure you can find out though.  Its been discussed many times.

1)  HD radio refers to a digital radio scheme using AAC-HE audio at about 48kbps streamed over the air.  Using a microphone to record FM radio doesn't get you closer to HD radio.
2)  Combining two copies of the same stream will not improve quality.

1) I read that HD radio was the dual streaming of both analog and digital audio. So, recording with the microphone would be analog recording, and the built-in FM radio recorder would be digital. That is why I said that it would be closer, since you are getting an analog ( but mono ) record from the mike, and digital off the built-in radio recorder. It's not the same as recording of HD radio ( analog and digital ) , but as close as you are ever going to get.

2) It will sound better. Not improve quality, but sound a bit better. I found this when I had to record with only a mike. Having one radio produced good quality sound, but having two made the recording sound better ( but not improve quality ).

ADC's are wikipedia eh ? Can't trust wikipedia. Can't trust it for everything. But yeh, I will search there for that , thanks.

Digital == AAC.  This is like saying if you take your MP3s, convert them to AAC, and then back to MP3 they're sound better because AAC is better then MP3.

No.

1) Analog will always have the better sound quality over digital. In Wav( or a old 1980 music record ) vs MP3, wav is the true uncompressed format in which the quality is much better. MP3, however is the compressed format that takes away the sounds that the human ears cannot hear, so sounds the same, but is actually not as good of quality.
2)Have you ever done this before..? It does sound better. With two radios, the sound is a bit louder, and produces a nice echo effect, or none at all depending on where you placed the radio's, which sounds better in my opinion. ( Which saying 'in my opinion' isn't really anything. ) To your ears it could sound worse, so just depends on the person.

I think you misunderstand.  HD radio IS compressed AAC audio:

Regardless, this is idea is pretty silly, not possible, and arguments about how HD radio works are off topic here, so I'm locking the thread.
