How to record to external device?

First of all, this is an amazing piece of software, thanks so much to the Audacity team who have created something so useful, and for free!

My question relates to playing an MP3 via Audacity, and then recording that MP3 into my Olympus digital recorder.

Why do I want to record the audio in real time? (instead of simply copying & pasting the mp3 to the Olympus) - well, it's purely because a natively recorded mp3 file on the Olympus gives more options with regards to what one can do with the file.

Does Audacity have a feature which can allow such a real-time playing of an audio to be recorded to an external device? Note, my Olympus has 3 ports: Mic / Ear / USB.

Many thanks!

Such as?

This pathway is not recommended because no matter what you do, you will be double compressing the MP3 and doubling the sound damage. It's one of the reasons we strongly discourage use of MP3 in production.

You said you don't want to use USB (digital transfer), the earphone connection is an output, and a line-level or headphone signal is about 100 times stronger than a mic signal so you won't get good results with the mic input.

Does Audacity have a feature which can allow such a real-time playing of an audio to be recorded to an external device?
Yes... But, of course you don't need Audacity to play an audio file.

Right. There's a piece of this we're not getting.

Such as giving the ability to add index marks.

I know I don't need Audacity to play an audio file, but I was thinking maybe there was a feature inside of Audacity from its plethora of options that aids such an endeavour (i.e. the recording of an audio to an external device).

Sorry forgot to mention - it's the Olympus WS-832.

Olympus WS-832.

Cool. I have two. Hold on to them with white knuckles. If you search for that model number now, they push you off to a different model that's much simpler (no more cool tricks) and doesn't have WAV support.

Audacity will do that on the timeline. The feature is Labels.

Yep, it's an amazing model; so many nifty features. I actually didn't realise how good of a device it was until months after I bought it. Was a bit tricky to get used to initially, but the more I used it, the more I appreciated it. I only have two problems with it, a) the quality of the speaker could be better, b) there isn't an auto turn off or auto stop play function after X amount of time.

I presume you're referring to the "upgrade" that is the WS-852/853. I was actually checking it out, and yeah, seems like It's just a dumbed-down version of the 832/833 series. Shame, I expected better from Olympus.

Really? I'm very surprised to hear that. I thought that permanent index marks on the Olympus was a proprietary feature, since, according to Olympus:

Writing an index mark or temp mark in a file enables you to quickly access desired position in the file with the same operations used for fast-forwarding, rewinding or skipping to the start of a file. Index marks can only be written in files created with Olympus voice recorders. For files created with other devices, you can temporarily store desired positions in the memory using temp marks.

But thanks, will check it out.

I don't think Labels is going to do what you want, but read up on it. Index marks burned into the sound file is what most people want, but the native WAV format doesn't allow that. That's the warning that it's going to fall apart when you leave the recorder.

Labels is a separate service and I believe it doesn't follow a file export. It's sometimes not all that valuable inside Audacity, either.


Olympus claims to be able to record from Something Else through the external microphone jack. (Click the graphic.)

They show it recording from one of their portable tape machines. Jury's out on whether it's mono or stereo. That tape machine (Pearlcorder S701 in my case) is mono.
