RockBox + Refurbished MP3 Players = Crowdsourced Audio Capture
An anonymous reader writes "Looking for an inexpensive means to capture audio from a dynamically moving crowd, I sampled many MP3 players' recording capabilities. Ultimately the best bang-for-the-buck was refurbished SanDisk Sansa Clip+ devices ($26/ea) loaded with (open source) RockBox firmware. The most massively multi-track event was a thorium conference in Chicago where many attendees wore a Clip+. Volunteers worked the room with cameras, and audio capture was decoupled from video capture. It looked like this. Despite having (higher quality) ZOOM H1n and wireless mics, I've continued to use the RockBox-ified Clip+ devices ... even if the H1n is running, the Clip+ serves as backup. There's no worry about interference or staying within wireless mic range. The devices have 4GB capacity, and RockBox allows WAV capture. They'll run at least 5 hours before the battery is depleted (with lots of storage left over). I would suggest sticking with 44kHz (mono) capture, as 48kHz is unreliable. To get an idea of their sound quality, here is a 10-person dinner conversation (about thorium molten salt nuclear reactors) in a very busy restaurant. I don't know how else I could have isolated everyone's dialog for so little money. (And I would NOT recommend Clip+ with factory firmware... they only support 22kHz and levels are too high for clipping on people's collars.)" This video incorporating much of that captured audio is worth watching for its content as well as the interesting repurposing. -
Ask Slashdot: Hackable Portable Music Player For Helicopters?
First time accepted submitter mrhelio writes "I work for a medium-sized helicopter company; we mainly fly tourists around on sightseeing flights. My company needs help finding a hacker-friendly portable music player for our helicopters. We have a problem with our onboard music players — mostly because it is an obsolete terrible design. The manufacturer has made an updated model, but it's basically the same obsolete design with the same terrible software and user interface. We are worried about spending $1000 per unit on these because the manufacturer will eventually stop making replacement units and then we will be force to buy upgrades for our entire fleet again and get everything recertified. (Any piece of equipment hard mounted in a commercial aircraft has to be certified by the FAA and it takes a lot of paper work, time and money for that to happen.) So we have a new plan: get portable music players like iPods, and plug those into the aux input in the intercom system. We need something that has nine hours of battery life, can hold at least three hours of music, and has remote control options for start, stop, volume, and selecting tracks and playlists, and a display that is visible in bright and sunny as well as dark conditions. The remote control option is the toughest part to find. The pilots need to be able to control the music without taking their hands off the flight controls for safety reasons. There are buttons and toggle switches already designed into the flight controls for these kind of purposes and we have mechanics/ engineers that can wire it all together, but the music player has to support the remote interface in the first place. Our first choice would be to give each pilot an iPod, but Apple is notoriously anti-hacking and anti-open source, plus you have to pay them ridiculous licensing fees to get access to their USB interface. So we are looking for a manufacturer that is open source / hacker friendly and makes something that meets our needs. Do you know of anything that would work for us? Maybe something that runs Rockbox? Should we just break down and design something from scratch like the Butterfly MP3 player?" -
Rockbox Developers Talk Open Source Firmware
angry tapir writes "I recently caught up with some of the key developers of Rockbox: An open source firmware replacement for the stock firmware shipped on MP3 players. The project, which has been active for over a decade, currently supports products from more than half a dozen manufacturers, including Apple, Arhcos, iRiver and Toshiba. It involves extensive reverse engineering to figure out how the devices' stock firmwares operate, as well as the challenge of developing for greatly varied targets. You can read the interview here (or the full Q&As with the project's founder and some of the developers involved in it)." -
After 3 Years, Rockbox 3.0 Released
DarkkOne writes "Rockbox version 3.0 is out. Three years in development, it marks the introduction of many new players since the 2.5 release and offers software-based playback allowing audio of nearly any commonly (or uncommonly) used format on a list of MP3 players by Apple, iRiver, Cowon, Archos, Toshiba and Sandisk. Beyond this it is FLOSS, under the GPL v2 license (or later), and includes a variety of plugins such as games and simple apps. 3.0 is the first official release for any players not made by Archos and more or less marks the beginning of a much more regular release cycle for the software." -

SanDisk Baits Apple And Woos Rockbox
An anonymous reader writes "CNET reports that SanDisk is courting open source developers to port Rockbox to its popular MP3 players. SanDisk is currently the world's second most popular MP3 player manufacturer after Apple. Rockbox is an open source OS for most major MP3 players. The article also talks about SanDisk's subversive new anti-iPod advertising campaign which calls iPod owners 'iChimps' and uses a 'street graffiti style' to create the illusion of a 'counter-culture uprising against the iPod'. The writer says, 'SanDisk is the first company to market its player as an ideological rather than technological alternative to the iPod. To do so is to fight Apple on their own terms.'" -
Improve Your iPod with Rockbox
polar_bear` writes "The allure of the iPod is undeniable -- they're well-designed, sleek little music players that pack a lot of features into tiny packages. However, iPods fail to deliver when it comes to support for free codecs like Ogg Vorbis, and -- let's face it -- iTunes leaves a lot to be desired. If you'd like to enjoy the hardware goodness of the iPod with GPLed firmware, give Rockbox a try. Tim Lord explains how over on NewsForge.com." NewsForge is also a part of the OSTG network, and Tim Lord is "timothy", one of our own editors. -
