Better to Upload Wav or Mp3 to Itunes
From .MP3, .M4A, .AAC and more than, there are many audio file formats you can expect to come beyond as a developer handling audio/video content in your application. Like in our terminal article The Consummate Image File Extension List for Developers , and The Complete List of Video File Formats and Codecs, in this article we'll delve into the different types of audio files, and how to choose the all-time audio file format for your application.
First, let'southward answer a couple of common questions:
What is the all-time audio format for sound quality?
A lossless sound file format is the best format for sound quality. These include FLAC, WAV, or AIFF. These types of files are considered "hullo-res" because they are improve or equal to CD-quality. The tradeoff is that these files will be very big.
What audio file format is best for use on the Web?
From a browser compatibility standpoint, .MP3 and .MP4 are the best audio file formats for use on the Spider web. All modern browsers support this format, including IE9. Other formats that are supported by most browsers include OGG, WebM, AAC, and WAV.
What is the most pop audio format?
MP3 files are the well-nigh popular audio format. In decades past, their ubiquity inspired an entire category of devices (MP3 Players), and their popularity continues to this 24-hour interval. MP3'south tin can be created in a diverseness of flake rates, which is used to balance the file's quality and size. Their efficient size has fabricated them the standard format to commutation sound on the Spider web.
How do I catechumen an audio file from one format to some other?
For converting files manually, employ a program like VLC Media Player to convert between popular audio file formats .
To programmatically convert files, Filestack offers an audio transcoding API that makes converting sound files a breeze. Acquire more on how to convert audio using Filestack.
Sound File Formats
.MP3
.MP3 files are the almost common audio file effectually. MP3s feature lossy compression, which means their quality will degrade over subsequent edits. MP3s are withal relatively large in size when compared to other audio file formats on this list.

.MP3 files can be encoded at a constant chip rate or variable bit charge per unit. A constant chip rate ensures the same quality throughout the audio file but results in higher file size. Variable bit rate detracts from quality during silent or near-silent moments of a file, resulting in smaller overall file size. Virtually smartphones and music players use the .MP3 format .
.M4A
.M4A is an Apple-based format that corresponds to .MPEG-iv video files. .M4A files characteristic lossless compression, assuasive for multiple edits without a loss of quality. Compared to the other sound file formats on this list, .M4A files take a similar quality but are lower in file size. You lot will see .M4A files play audio on Apple products such as iPhones and iPods.
.AAC
Similar MP3s, Advanced Audio Coding (AAC) files are also lossy audio files. However, .AAC files, in their original state, are much higher in quality than whatever of the other sound file formats on the list. .AAC files are generally like in size to MP3s, despite existence a tad higher in quality.
They can too exist created with a variable fleck rate or constant scrap rate. .AAC files are also open-source, which ways yous don't need to pay royalties to create and distribute them (different .MP3 files).
.AAC files are most normally associated with iTunes, though they tin exist used on other role player devices and gaming consoles .

.OGA, .OGG
Similar to .AAC files, .OGA files are open up-source and employ lossy compression. They employ variable flake charge per unit to cut down on file size. Nonetheless, this doesn't detract from the overall sound quality. In fact, .OGA files tend to be higher in quality than MP3s. .OGA files aren't supported past many programs – especially compared to the rather ubiquitous .MP3.
.FLAC
Like M4A, FLAC is a lossless audio format. Unlike M4A, FLAC is open source and features a more efficient compression algorithm, which can reduce the file by 50-lxx% over its original size. This format is popular among audiophiles as a way to store collections of music in their highest quality class. Because it is open source, it is uniform with many devices and programs.
.PCM, .WAV, .AIFF
PCM, or Pulse-Code Modulation is an uncompressed audio format that is commonly used in CDs and DVDs. This format uses a "sampling rate" which defines how ofttimes the original sound was sampled, and a "bit depth" which defines how many bits are used to define each sample.
WAV, or Waveform Sound File Format is commonly used as a wrapper format to store PCM format audio, making it more suitable for Windows computers.
AIFF, or Audio Interchange File Format, similar WAV, is commonly used as a wrapper format to store PCM format audio, except for Mac computers.
How to Choose the Right Audio File Format
Choosing the correct audio format depends entirely on what you program on using the audio for. You lot should choose a format that achieves the quality of audio you crave, but aught more. Unnecessarily high-quality audio files can exist unwieldy to move, share, convert, and manage. Consider a couple of scenarios:
- If you are a professional that is planning to edit the audio (for a podcast for example), then apply an uncompressed format . This way, you volition maintain the audio's quality each time you edit and salve the file. When you are finished, you can export to an easier-to-distribute compressed format. Uncompressed formats include PCM, WAV, and AIFF.
- If yous are an audiophile wanting to listen to your music collection in hi-fidelity, choose a format that uses lossless sound compression . You will use less storage than an uncompressed format, only still retain the full quality of the original recording. These formats include FLAC, WMA, M4A.
- If yous are non concerned with perfect audio quality, plan on sharing the file on the Web, or need to conserve disk space, choose a format that uses lossy sound compression . Luckily, lossy compression has become so good in recent years that most people tin can't tell the difference betwixt lossy and lossless compression. These formats include MP3, OGA, AAC
Decision
In summary, the almost popular audio file types are:
- .MP3
- .M4A
- .AAC
- .OGA
- .FLAC
- .WAV
- .PCM
- .AIFF
At that place are certain times when it is best to use one file format over another, and often, you accept to convert between file formats. To programmatically convert betwixt audio or video file types, you can use Filestack's sound & video transcoding API . Filestack's API as well supports extracting audio files from video files, cropping or resizing video files, extracting thumbnails from videos, and more. Become started for free with Filestack today.
