Recording live sound

Much depends on the sort of quality you need and the duration of the performance.

Smartphones, tablets, digital memo recorders and suchlike are capable of recording but due to the size the quality isn't great and in some cases the duration they are capable of would be limited.

Whatever system you choose will provide a problem because recording the choir will be relatively easy but recording you singing with the choir will be more difficult. A microphone would need to be carefully placed on a stand close to you perhaps or you would need to hold it or you could stand apart from the choir.
The logistics will be for you to sort out with the choirmaster and the other members...

The device is another matter. The simplest would be a quality cassette type tape recorder. These have been obsolete for years but there is still quite a few around. Even better would be an old reel-to-reel tape recorder but those are now few and far between. The advantage of these are they just need loading with tape and switching on...

Some video cameras have amazing stereo sound and in particular the VHS video camera/recorder. Other cameras have sound capability and sometimes it is very good so they are another option....

Perhaps the best option for these modern times would be a half-decent laptop computer loaded with recording software. There are many programmes available and some are free and some will turn the laptop into a virtual recording studio. Goldwave is free, and very stable and reliable but it can be tricky to make it work. Add a compatible microphone and you are all set. The better the quality of microphone the better the results will be.

Happy singing!

1) You can use Sony's Sonic Stage software to do a digital transfer of the mini disc to a .wav file. Sonic Stage is slow, but it is a very high quality digital transfer.

2) It's not like you are digging a ditch and getting worn out. So what if it is a real-time transfer? Find something to do. Read the New York Times on line. Make coffee. Call a friend.

3) There is nothing wrong with a good old-fashioned analog transfer (using the MD's analog output) into your computer's audio recorder (such as Audacity) - which gives you a digital file. That will be just fine for practice CDs for other choir members.

4) You can buy an MD deck or portable with a digital output - such as a Sony 940 or 640. There are many others.

Is the recording media "full" (you need to delete some videos) or it is "broken" (cannot record onto it).

Perhaps your computer's sound card is unable to play back at the bit rate and kHz you are recording at on your (mobile?) recorder. I'm not familiar with the RC-50 but if you are recording at 24 bit for example and your computer's sound card is only able to play back at 16 bit it may not reprosuce any sound. Usually you will get an error saying so. Have you tried different playback software?

Joe I can only give you what I had learned over the years recording Cantatas and choirs and soloists in church.1) If your mikes have switches TIE THEM WITH DOWN WITH DUCT TAPE You ask why I had artists that turn the mikes "Off" just for fun and after the session ask for a copy of the recording if it came out good. I disabled the switches in my mikes. 2) Put your mikes not at the artist but a little distance from them for is it is a sermon the preacher moves his/her head talking to the crowd.3) SERVICE your recorder and MAKE SURE THE HEADS ARE CLEAN USE VIRGIN TAPE if possible because there can a speck of the magnetic material come off and this prevent your erase head doing its work properly 4) If you record music, try to go to the practicing sessions so that you can grasp an idea for the optimum placing of you mikes. Keep your levels UNDER the "0" mark I leave them at maximum 10dB below the zero mark. Practice and try different positions of your mikes till you are satisfied. If you can invest in a microphone mixer and employ multiple mikes.5) If you buy a recording set get the most expensive cardioid microphone you can afford. If you upgrade later then just carry your mikes over to the new set.Why cardioide or heart shaped mikes they cancel out background noise.I did this the times that I did a lot of recordings. I have AKG UHER Sennheiser units that give me stirling service since 1966 I clip the plugs off about 40 mm from the plug and then resoldered the plugs back on I had no cable giving grief during recording sessions Have a spare mike on standby just so that you have no Murphy's law cases! HAVE FUN

connect your nokia phone with usb device,then goto the audio folder ,copy the voice recording you made,and just paste it onto your pc.

Sounds like you do not have your audio recording source set correctly.  If you're recording from a file on your computer or a CD via the CD-Rom drive of your computer, you need to probably set the recording to either "Wave" or "What you hear", one of the two.  The "What you hear" can be easiest, but then again, if any other sound comes accross your computer at the same time, you'll end up recording that as well, so it's best to stick to "wave" if you can... or make sure all Windows sounds are turned off (Audio settings ->Sounds ->Select "No Sounds" as the theme).

maybe the recording device it's not selected properly

Get the song onto your computer in QuickTime ".mov" format and you can change its speed as well as pitch. You may need to buy QuickTime Pro, but it used to be less than $30. Get it from Apple. PC or Mac version as needed. I do this often with songs for rehearsal with my choir.

do a clean if that doesnt work you will have to format it
