iAUDIO
iAUDIO is the brand name for a range of portable media players produced by Korean consumer electronics and software corporation Cowon Systems, Inc.
The iAUDIO range consists of players based on both flash memory and hard disk drives.
The CW200 had audio playback capabilities, an FM radio and voice recording through a built-in microphone.
Upgrades from previous players came in the form of UMS standard, BBE sound processing effects, line in recording and a 124 colour backlight LED display.
WMA, OGG, ASF, WAV, and MP3 music files can be transferred between PCs and Macs using USB 2.0 or direct input.
When the iAUDIO M3 was first released outside of Korea, there was a quality issue with the player's remote control.
This issue was rectified by the rapid recall of all faulty remotes and free replacements.
It was also Cowon's first player to feature a navigational joystick instead of the 2 rockers found on most previous releases.
The U2 is smaller and lighter than the iAudio 4, measuring at 2.9x1.0x0.7 inches and weighing 1.2 ounces, and features a 128x64-pixel display.
The only difference between the two players was that the G3 was powered by an AA battery, allowing a playing time of up to 50 hours.
The 20 and 30 GB X5L models specify a rated playback time of 35 hours with a 2250 mAh battery.
Its successor, the X7 series, was slated to be released at some point in the summer of 2007, but was delayed until October 2010.
Another new feature was the U3's powerful sound output of 30 mW per channel (at 16 ohm, achieved by utilizing the new Telechip TCC770 audio chipset and Cirrus Logic CS42L51 Codec).
With the firmware version 1.20 Cowon added ID3 browsing and DRM capabilities to the U3.
Features: The iAUDIO was presented in January 2006 at the CES in Las Vegas.
This technology allowed the production of a high capacity digital audio player in a very small form factor.
The iAudio F2 has a 1.3-inch display with 128x160 pixels, up to 2 GB of flash memory, line-in recording, 22 hours of audio playback on a single charge, and the usual Cowon supported codecs: MP3, WMA, WAV, OGG Vorbis, and even FLAC for lossless audiophiles.
The OLED screen from the iAUDIO 6 model was replaced by a TFT with 260,000 colors (18 bit colour depth).
Audio recordings could only be saved in WMA format, with a user selectable bitrate of 64, 80, 96, or 128 kbit/s.
The device played MP3, WMA, FLAC, Ogg Vorbis, WAV, and ASF audio files as well as Xvid videos.
The iAudio E2 has no screen which means it fully operates four buttons, two on each side, and voice cues.
It includes a 30mW headphone amplifier, video connectivity (through an extra cable), a microphone, and an FM radio (to record voice and broadcasts).
It also supports a variety of audio formats (including rarities like FLAC and OGG) and USB mass storage.
[8] It features a new vertical form factor and improves upon its predecessor by the inclusion of a built-in speaker.
[8] All Cowon media players, starting with the iAUDIO 4, feature a set of sound enhancement technologies collectively referred to as JetEffect, including a technology known as BBE+, licensed from BBE Sound, Inc.
It included an updated reverb algorithm, allowing the user to choose between nine different types of reverb timbres, including Chamber, Room, Club, Hall, Auditorium, Cathedral, Stadium, Canyon and Long.
