MP3 players with variable playback speeds

by Jasmine France

The Sansa Fuze offers three playback speeds--fast, normal, and slow--for podcasts and audiobooks.

As its title may suggest, an MP3 player's primary duty is to play MP3s, which are more often than not music files. But audiobooks, podcasts, and other spoken-word content enjoy plenty of face time on portable audio devices, and why not? They offer an informative and entertaining way to pass the time. But for those of us who prefer our information and entertainment in condensed form, time is of the essence. Spoken-word content is one type of audio that (generally) doesn't sound completely absurd when sped up, and doing so gives the listener a way to get through said files with due haste.

Luckily, there are a handful of MP3 players on the market that offer a feature known as variable playback speed, which allows you to speed up (or slow down) audio on-the-fly--no clunky software conversions required.

Check out MP3 players with variable playback.

For more than five years, Jasmine France has covered a variety of tech products for CNET--from scanners to keyboards to GPS devices--but she's happiest where she is now: sitting atop a pile of MP3 players, "testing" every music service known to man, and jamming a variety of earbuds in every shape and color into her absurdly small ears.

Why oh why have MP3 players regressed since the Creative Nomad Jukebox 3 was introduced in 2002, with its *pitch controlled* variable speed playback (though it doesn't have enough slower speeds for spoken word)? The Jukebox 3 also *records*, in high-quality WAV or MP3, from line-in or optical-in! Runs on one or two replaceable batteries. Two line-outs (in addition to headphone out), with front and rear speaker emulation. 20dB boost for microphone recording. Firewire or USB.

I'll stop. And admit that the thing is the size of a portable CD player before the first "slim" CD player was ever marketed. And weighs more. But miniaturization should have allowed some of those features to soldier on 7 years later.

I'm quite happy with my Samsung yp-p3 16 GB mp3. I bought it because of its DNSe 3.0 feature which gives me 3 levels of slow and 3 levels of fast variable playback speed. I have a lot of audio files that I've ripped from their original CD formats--and they all sound great at a slow -2 setting. All my audio files are actually study notes that I've recorded from lectures, audio-extracts from video lectures, text-to-speech files. I also have a lot of trance music that I listen to when I work out. Wow--those fast Tiesto tunes even sound more "enTRANCING" at a +1 speed==gives me a great push on my cardio exercise. Then I switch to -1 speed to slow down my already slow Pink Floyd tunes==great partner when I do my weight exercises. After my workout, I keep the -1 slow setting to play some Enigma==what a "chilled-out" listening experience. DNSe 3.0 sounds excellent no matter what playback speed!!!!!!!!!!!!!!!!!!

I've read some news that Samsung is incorporating its DNSe 3.0 into their high-end smartphones. I hope to see some models soon.

Don't leave out the Cowon S9. It'll let you change the speed of audio from 50% to 150% in 10% steps, and you can do the same with video playback. Both let you choose to keep the pitch the same or let it change with the speed.
