MP3s and MP3 Players

Without MP3 files, where would the world of podcasting be? We love MP3s and this page looks at the format and some of the players in the Player world.

We featured mp3 files and players in Show 11.

You can listen online with our pop-up Pod Player, save as MP3 or subscribe via iTunes.

What is MP3?

OK, so you've come across the term MP3... and hopefully listened to one of our podcasts in MP3 format... but what is it?

MP3 is an audio compression format, used to squeeze audio into a small file. The full name for the mp3 format is MPEG-1 Audio Layer 3. As far as the world is concerned, mp3 is a small, convenient way to copy, transfer and listen to music. The format is what's called 'lossy', meaning that the act of compressing a music track loses some of the original audio data - ideally in a way that the human ear doesn't notice.

MP3 files can be played on a range of devices, including desktop PCs and MACs, mobile phones, PDAs and of course MP3 Players. This makes them an ideal format to back up your media - such as cassettes and vinyl. For more on the subject of archiving your audio, take a listen to Show 21 of our podcast, where we cover this on more detail.

Is the iPod 'all that'?

80% of the players out there are iPods, so Apple must be doing something right. Sure, they're stylist products with a great name, but can you get something better for your cash? On Cast 11, we compared the iPod video with the Creative Vision:M and found which was the best buy. Controversial, but the Vision:M won... Here's our comparison chart:

	iPod Video 30gig	Creative Zen Vision:M 30 gig
Battery life	Up to 14 hours	Up to 16 hours
Size	103.5 × 61.8 × 11 mm	104 x 62 x 18.6mm
Audio formats	MP3, AAC, Protected AAC (Apple iTunes), Audible, Apple Lossless, AIFF, WAV	MP3, WMA, WMA (with PlaysForSure), Audible, WAV
Video formats	H.264-LC , H.264-BP and MPEG-4 SP MPEG-4 or H.264	WMV9, MPEG-1, MPEG-2, MPEG4-SP (inc DivX 4 & 5), XviD, Motion-JPEG
Extras	Supports iTunes music store Mac Support	FM radio Voice recorder Organiser software (Calendar / Contacts / Tasks)

The Vision:M wins for us, with it's FM radio and wider choice of supported formats. It also isn't tied to Apple's iTunes, meaning you can get MP3 files from a wider range of stores, and move them around.

Cassette to MP3: Stuck with stacks of cassettes in a box taking up space? Never listen to them, but daren't throw away those precious audio memories? Well, give those old C60 and C90 audio cassettes a new lease of life by copying them to MP3 format. The Plus Drive Cassette Converter can be installed into your PC, allowing your PC to play and convert audio cassette tapes. The Plus Drive has auto-reverse and comes with the required connectors and software. Once converted, you can transfer your audio to your MP3 player, and listen again to all those old memories, before your cassettes deteriorate with age. For us, this one's a must. We've got one, and have reviewed it on our Plus Deck page...
The Plusdeck is available from gadget guys Firebox and Maplin.

There's also a USB twin cassette deck version available from Firebox and Maplin.

FM transmitters for MP3: In December 2006, the UK Government finally agreed that the previously-banned FM transmitters used illegally by many people in the UK to re-broadcast their MP3 players to their in-car FM radio... could now be used legally.
If you want to get your MP3 player transmitting to your FM radio, take a look at the range of short-range FM transmitters at AdvancedMP3players , Add Ons World and Play.com. Prices start from around £10. iPod users may want to try the Griffin iTrip.

More on MP3 formats

Here's a little more information on the MP3 audio format. There are two key numbers associated with MP3 files, the encoding bitrate and sample rate. Here's a quick look at what they mean... so you can show off your knowledge to your friends...

Bitrate: This represents the number of bits of data being processed per second. This value has an impact on filesize and quality. As a rough guide, here's a summary of the type of quality you can expect from an MP3 file at various bitrates:

8 kbit/s — Telephone line quality
32 kbit/s — Speech (medium wave radio quality)
96 kbit/s — Speech with music (FM radio quality)
192 kbit/s — Pretty decent quality, most unlikely to notice a difference with CD
320 kbit/s — High quality, almost no audio loss

Sampling rate: Number of digital samples of audio taken per second - measured in kilohertz (kHz). The most common sampling rate is 44.1kHz, which is used for CD audio

If you want to find out more, see the Wikipedia MP3 entry

Other formats

If you're more interested in quality-vs-quantity, there's a small number of lossless audio formats out there - notably: Apple Lossless Audio Codec (ALAC or M4A) for your Apple iPod or the iPhone, FLAC (Free Lossless Codec) an open-source format, or Windows Media Audio Lossless (WMA) which is supported by Microsoft's Windows Media Player version 9 and above.

MP3 FAQ

Converting Apple Music	If you've bought your music from Apple's iTunes / iStore, you'll probably have them in the Apple AAC Protected format, which means you can't use iTunes to convert them to MP3 for use on a different MP3 player. There is a workaround though. You can use iTunes to burn a copy of your music onto a CD, then use 'Ripping' software to convert the audio to MP3 - This is a little time-consuming, and there's a quality loss, but at least there's a way to get music that you've paid for... on another device.
Where can I get MP3 audio?	If you're looking for a good collection of audio books, MP3 files and podcasts, try Audible.co.uk and Simply Audiobooks. Users of the iPod may want to take advantage of the iTunes podcast feeds (see www.apple.com/itunes/podcasts). There's also www.napster.co.uk
Shrink my MP3	In mid-2007, a service called ShrinkMyTunes appeared, claiming to offer to increase the storage space of your MP3 player by 4 times - this is achieved by compressing your audio files down in a way that should be inaudible to listeners. Find out more on our ShrinkMyTunes page.
How do I convert to MP3?	If you want to convert an audio format such as WAV or WMA to MP3, there are a number of converters out there. Our favourite is Easy CD-DA from www.poikosoft.com. You'll also find that the iTunes software handles conversion of some file types to MP3.
Problems connecting	Having a problem connecting your MP3 player to your PC? Here are a few suggestions: Try using a different USB port on your PC Try using a different USB cable, in case the cable is damaged Ifyou're using the software that came with your MP3 player - try re-installing it, or checking for a software update from your MP3 player manufactuer's website. Try using Windows Media Player, which supports connection of external mp3 devices Check in Windows Control Panel > System > Hardware > Device Manager, to see if your player has been found and isn't disabled Make sure your PC is up-to-date with all patches installed Try connecting to a different PC If you're still having problems, try asking in the Handheld Audio forumstating what you've tried and what OS you're using.
