Sometimes audio comes in a format that might not play on your iPhone/iPod/iPad. For example, you may have downloaded songs from the Internet, and then find that they won鈥檛 work on your iPhone or on iTunes. In cases like these, you might find that you need to convert the audio before it is usable. This can be especially true when you鈥檙e transferring songs from computer to iPhone. That鈥檚 what iTunes converter can help you.

What Audio Formats Does iTunes Support?

iTunes converter supports various audio formats, including:

-- MP3. This is one of the more common types of audio formats, and most songs that you download online come in this format. For example, you can buy music on Amazon in MP3 format, and it is often DRM free. Most audio players can play MP3鈥檚. The downside to this format is that the files are compressed, so there can sometimes be loss of quality. It鈥檚 the major format that iTunes music converter supports to convert.

-- AIFF. This is a non-lossy (is not compressed) file type that was developed by Apple in the 80鈥檚 and is still used today. However, it uses a lot more disk space than MP3 because it is uncompressed. This format is commonly used to capture sound data from CD鈥檚.

-- WAV. WAV is another common audio format. It is not compressed, so it takes up a lot of disk space. However, it is easy to edit and most audio editing programs can output to this format.
-- MPEG-4 (MP4). This is another common format that is often used to store videos, but can be used for audio as well. It is generally higher quality than MP3, and is lossy like MP3.
-- AAC. This stands for Advanced Audio Coding, and is an audio coding standard developed in the 90鈥檚. Like MP3 and MP4, it is compressed, so it is lossy and can lose data if you are converting from a non-lossy format.
-- M4a. This is Apple鈥檚 own lossless format for media.
-- All of the QuickTime formats, such as AAC and Audible books.

Will iTunes Converter Reduce Sound Quality When Converting?

Whether converting will reduce sound quality or not really depends on the situation, no matter you are using iTunes converter or any other third-party converters. Generally, a reduction in sound quality occurs when you lose data, and that can happen for a number of reasons:

  • You convert from an uncompressed format to a format that is compressed. (For example, you convert from MP3 to WAV.)
  • You convert from a compressed format to another compressed format. (For example, from MP3 to AAC.) Think of decades ago when people used to copy from one VHS tape to another, and each time there was a loss of quality (data), until it was unwatchable. This is a similar concept.

However, you will NOT usually lose sound quality if you:

  • Convert from a compressed format to an uncompressed format. (e.g. From WAV to MP3.)
  • Convert from an uncompressed format to another uncompressed format. (e.g. From WAV to AIFF.)

About Compression

It may sound like a bad idea to compress music based on the above information, but that鈥檚 not necessarily true. Though it is true that compression can destroy data, the payoff is that you can store a lot more music on your phone or hard drive.

Sometimes if you compress audio too much, you can hear the difference and the file sounds bad. A lot of the time, though, your ears may not notice the difference. The trick is in finding the balance.

Note also that you can鈥檛 鈥渦ncompress鈥 a song after you have already compressed it to get the quality back. The data just isn鈥檛 there, so you will only succeed in making a bigger file with no added benefits if you, say, convert from MP3 to WAV.
