Title: Best recorder that rockbox supports?
Post by: Bedlore on June 02, 2010, 08:30:00 AM
I've now used my iHP-140 for years and modded it to include a clock.  I do have a soft spot for iriver but I'm not sold to any brand specifically.  I'm interested in hearing what others have to say about what and why they consider to be the best rockbox supporting device for recording, as well as playback of course.

The iriver H140 still wins in terms of convenient, useful I/O ports.

What about the H300, doesn't it have the same I/O's but with a better screen?

Nope. It lacks the optical input and output entirely.

Searching the internet is a good start...

This topic is one I have found very hard to find reliable and detailed information on.

Also recording means different things to different people.

I am partial to FM recording specifically lectures and recordings
for podcasting of human voice as opposed to microphone or
LINE IN recordings.

The best recorder I have found is the Sansa Fuze+

Bear with me while I explain what I mean: 
Regardless of Rockbox's support for this unit's recording
capabilities, it is easy to dual boot into the original firmware,
record FM or mic, and then reboot into Rockbox for playback.

The original firmware has the best FM tuner and ADC
hardware I have encountered.  Also the user interface
allows saving and restarting the recording process
during the applause between speakers.  The resulting
recordings are WAV files at 1411 kbps and in stereo.

That means raw 44.1 KHz sampled 16-bit dual channel
WAV files.  Same as CD blue book specs, not lossy
ADPCM style compression.

The older Sansa e280 OF produced 512kbps FM recordings
also in WAV format but not at Blue Book quality.

Do you want your recordings in OGG, FLAC, MP3, AAC,
Speex, Opus, or WavPack?  Dont make Rockbox
record it in that format.  Doing that cuts down on your
Recording Battery Life.  Instead, maximize the duration
of your FM recording time:  Boot into the original
Sansa firmware, record in wav format and transcode
it later using the quality settings you really want.

All the command line encoders accept WAV input.

Make the audio file formats that you are comfortable
with, but start with high quality input. 

And that means Sansa Fuze+ Plus  :)

PS: I get about 7-7.5 hours of FM recording time on a full charge, so you need to start with at least 5GB free.  Thus I do not recommend buying the 4GB Fuze+ unit as the battery will last longer than the memory  ::) and you cannot record directly to an SD card.  :P

I would be interested to learn if LINE-IN recording is possible with this device.

I guess Sansa Fuze+ does not have line-in.

Iriver H120 is also able to record in stereo waw and different sampling. I did not test it, but it might have good A/D converter. At least the D/A converter is subjectively better in H120 than Sansa Fuze+. I have both, so I may compare.

The only thing that I hated on H120 was the ocasional sound of spinning HDD if internal microphone was used. I was forced to use external mic, but after replacing internal HDD by SDD, no problem.

The optical input and output are just great. Beware optical input is usable only with Rockbox, OF adds regular clicks in recorded sound (if digital input is used). It may be easily processed out (it is one, probably intentionaly wrong, sample every while), we did it in MathLab, but it is anoying...
