    Ogg support is very nice, but I hope this device can play other formats as well. One of the things that is making media-playing consumer devices so popular today is the support for all different formats of media. DVD players that can play every type of file format out there, and car cd players that can play mp3. The key to success is multi format support.

      It can currently play Ogg, mp3, wma (non-DRM), and wav.

      People are also working on other alternative codecs, including FLAC, musepac and a few others I've heard talk about in IRC.
    • For a device supposedly aimed at developers, and with as big as of a hard drive as this thing has, why doesn't it support FLAC?

      (What would be doubly-nice is if it supported real-time recording to FLAC from a line level input, but I'll bitch and whine about the absence of that feature when they get around to having it at least *play* FLAC...)
      • The problem, I believe, is space in the CPU's memory for the codecs. The thing has 64k (yes, k) of memory for running the firmware and decoding audio. Multiple codecs have to be loaded into the chip on a per-song basis.

        Also, I don't know what FLAC would do to the battery life. Since the data rate is so high (compared to a lossy format) you'll be running the disk A LOT more.

          The disk would be running less than recording a line input at 44.1Khz WAV though. The reason I mention this is that a couple of my friends are audio engineer types and keeping an eye open for an iPod-like (loosely speaking) that has lots of storage, can record full quality audio at line level, and perhaps compress to lossy format as well, without shelling out thousands of dollars for "professional" solutions. On-site recording would be less of a need than a portable music library, but if they can kill two birds with one stone... why not?

That's why they're not included in US Linux distributions. They don't have a licensing deal with the company that owns the MP3 patents, so they can only be distributed in source code form, and you have to compile them yourself. Of course, if you do this and then encode some MP3s without paying a license fee to Fraunhofer/Thompson, then you're a criminal...

    I actually have a Neuros. I bought one about 2 years ago. Honestly, they're a lot larger than ipods, so I doubt that they will catch on with the portable audio market. It's not really 'pocket-size.'

    However, it is perfect for carrying in a backpack. The built in mic is sensitive enough for recording interviews, and the harddrive can hold alot more than other portable recorders you can buy.

    The sound quality is decent, but the included headphones broke within two months. I did go jogging with them, so that might be the reason.

Thats why I picked up an MPIO FL300 (matchbox size, literally, it fits inside a matchbox), which is flash based and at 1GB enough songs for running and exercise. I've figured that I should use two, one for exercise and one for "sitting still" like on a train and in the car. Will this thing work well that way or will I still have problems on bumpy roads? Al

        That's what the Neuros flash backpack [neurosaudio.com] is used for. The design totally rocks, you have a single player that can have a hard drive backpack for normal use, then switch to the flash backpack for doing high impact activities.

    • The key to making the FM transmitter work in DC/Baltimore is to make sure the Neuros is plugged into your ciggarrette light adaptor. Or just take off your external attenna.

      I took off my attenna because I was tired of people changing the radio station on me (I listen to European metal for the most part and the radio sucks) and my Camaro looks better without an attenna :)

    This would be an awsome product to hack on. I've been thinking about putting together a car-based mp3 player, and with the firmware now open and most of the functionality there that I want, this might be a better platform to work off of. I was originally planning on going with Mini-ITX hardware (or nano-ITX when it came out), Linux BIOS + LFS system on CF, and entirely custom software (with heavy using existing libraries). This would be much simpler, and result in just as good of a system.

    On the I don't think it stands a chance at doing well in the marketplace though until it cuts it's size down some. The seperate player and hardrive backpack is fine (and infact prefered) for a car based system, but way to clunky for a handheld.

    Lastly, speaking of OGG has anyone had any real-life experiance with the MPIO HD-300? I saw it in Best Buy, and it looked like a really nice system - 20 GB, about the same size as the iPod, felt solid, played OGG MP3 and WMA, was 20 bucks less than the iPod, and supposedly has significantly better battery life. This claim is backed up by the fact that in the past thier flash models have had the best battery life in the industry. On the other hand thier website has horrible english, so I would expect support to be lacking, and I can't find any sites that have actually reviewed the device (just regurgitated the press release, let users post uninformed opinions, and then called it a review). Anyone have some real info to add to this? Especially about its reliability/quality and how well it works with Linux?

    I've got a Neuros...the USB1.1 version from about two years back. I gotta say -- it's a sweet device.

    -- I like the swappable backpack idea because it makes for cheaper upgrading and the ability for more than one person to use the same device with minimal difficulty.

    -- I absolutely LOVE the integrated FM broadcast. This hit the market before everyone and their mother was making add-ons for this functionality, and it's still a really handy feature. It means that _I_ always get to hear my music in other people's cars, because no one else has this ability!

    -- HiSi (the song-identifier) is a pretty nifty gimick, too, although of minimal use (more to the point is the built-in FM reciever...something that I think EVERY audio player should have -- it costs about 20 cents to include at this point, why not do it?!?!)

    (disclaimer at this point -- mine IS the old version)

    !!!HOWEVER!!!

    The one failing of the Neuros is in its interface. Navigation is painfully slow. You cannot queue up songs while it's playing. Organizing songs into playlists inexplicably takes about 3 or 4 seconds once you've decided upon a song and selected "Add to my playlist". There is no way to play a series of albums, so you are stuck playing alphabetically by song title, by artist (and then within the artist by song title) or album-by-album. See previous statment about creating custom playlists. Oh yeah, and for some reason, it takes about 3 seconds to boot each time you start it. My PC starts faster!!

    So, to put it lightly, the interface plain SUCKS! And ultimately, that's what matters. I love the tech aspect of this device. The open-standards are awesome (ogg support used to require a separate version of the firmware -- dunno if that's still true); there's a thriving developer's community which is fully supported by the company. Their customer service is phenominal (a broken mini-audio jack took 5 days to fix -- shipping time to Chicago included!). But the interface needs a lot of work.

    And the interface of an audio player is the make-it or break-it point, IMHO. It's what you see every day. How quickly can you play your music? Good interfaces are invisible. You don't notice that they are there. You just notice that you can get the job done and do it quickly. I think this is more important in the portable-audio market than anywhere else. If I have to make the decision whether or not to turn on my device because there is a 10-second lead-in before music starts and a 5-second end sequence, then they've lost me...

    I haven't had a chance to get my hands on a generation 2 device yet, so perhaps there has been a massive improvement. However, as of now, my next audio player purchase will be an iPod -- unless someone can point me to a better interface!

    Regardless of the open source version's merit, you turn people off at step one. Now, I don't know what Apple has done to you, but a killer audio player is not formed out of spite for large corporations or the mainstream. It is made based on realizing where current players falter (battery life, size, UI) and improving on those. Nobody cares if the firmware is open source except the esoteric readers of Slash.
