Though not the highest quality, it has enough other benefits to compensate. An MP4 audio file is often mistaken as an improved version of the MP3 file. The two are completely different and the similarities come from their namesake rather than their functionality. Also note that the MP4 is sometimes referred to as a video file instead of an audio file. An MP4 audio file type is a comprehensive media extension, capable of holding audio, video and other media. The MP4 contains data in the file, rather than code.
This is important to note as MP4 files require different codecs to implement the code artificially and allow it to be read. The waveform data stored presents an image that demonstrates strength of volume and sound in specific parts of the WAV file.
Also, the WAV is typically used on Windows systems. The easiest way to envision this concept is by thinking of ocean waves. The water is loudest, fullest and strongest when the wave is high.
The same holds true for the waveform in the WAV. The visuals are high and large when the sound increases in the file. What makes so beneficial is its lossless compression, retaining high audio quality throughout all types of restructuring processes. As you may already know, the WAV is the go-to file type for recording, mixing, and mastering. Also, it is widely recognized as the professional audio format. This means that the majority of uploads, be it to Apple Music, Spotify, or any streaming service will support and sometimes even demand a WAV file.
Conclusion :. Although this list does look at the technical factors behind which audio format is best, we recognize that personal preference goes a long way in determining what is best for you.
Knowing the different file types, which are best to send, and which may be best to use only for personal preference can help make you a consistent and reliable engineer.
Top 10 Audio File Formats. Uncompressed files are the format choice of professional audio engineers. Lossless files compress the data but do not delete it. The MP3 is the most popular lossy file available. Any audio file with a sampling rate and bit depth is a PCM file. DSD files are unplayable without the D to A converter needed to play them. Ogg Vorbis Logo. Spotify uses the Ogg file for its streaming service.
WMA files can be either Lossless or Lossy. Playing WMA files on a Mac computer requires third-party software or file conversion. The MP3 is the most common audio file available. FLAC files are an incredibly popular lossless audio file format. WAV files are the go-to uncompressed file of the audio world.
PCM files come in bit-depths of either 16, 24 or 32 bits and sample rates range from Not to mention that such files are complete overkill. In the old days of slower broadband, copying data from physical CDs was the best way to grab raw PCM audio. These days we have lightening fast broadband, and so there are a few download and streaming services that you can can find these tracks on.
When it comes to lossless audio downloads, FLAC Free Lossless Audio Codec has been growing in popularity and is now the go to format at a number of high-quality streaming services. FLAC offers exactly the same audio quality as raw PCM, but manages to compress file sizes by around 30 to 50 percent, depending on the encoder and track contents. It might help to think of this as somewhat similar to a. Apple has its own version of lossless audio which it calls ALAC.
The three services that have made the list below offer FLAC streaming and also have dedicated Android apps so that you can take your lossless collection with you on your phone or tablet.
MP3 is certainly one of the most popular audio formats, but the standard is much derided by audio enthusiasts for cutting out content. MP3 works by splitting a track up into sample frames, and Fast Fourier Transforms FFT are used to obtain frequency data from these frames.
This frequency data can then be analysed for masking opportunities, where data can be quantized rounded to lower bit-depths to save on space, which varies based on each frame. It reduces the quality of the music content, directly affecting the listening experience. For some this loss of quality is not an issue and at times, not noticeable at all. For casual listening, it can be acceptable. WAV stands for Waveform Audio. Although it can be a container for compressed or uncompressed files, it is commonly used as a container for uncompressed PCM files so that it is playable on Windows.
It supports sample rates up to kHz, bit depth up to bit. It is a HD format, no additional processing or encoding is applied. As it has been around since , it is compatible with all players, hardware and software that can deal with digital files. Around , Apple developed this format, for Apple products, around the same time as the first iMac. It is very similar to a WAV file. It is also a HD format. The only difference is that AIFF files have better support for metadata tags.
When entering additional data such as album title and genre in a media player software, the data gets added to the file. This does not happen with WAV files. As the name suggests it was developed by Apple and uses lossless compression. It is a part of both Quicktime and iTunes. When played back, they are uncompressed and sound identical to their original source.
It is supported by many software media players on both Mac and PC. However, take note that they are been converted to MP3 for streaming. In Google Play Music case, it will convert it to kbps. Although lossless files use more internet bandwidth to stream, the advantage over lossy formats is the preservation of the audio quality. If you play most of your music from a computer, there will be no issues with this format. Mobile playback options need more consideration.
Like the OGG format, it is open-source. In these situations, you want as little latency as possible. Latency is a time delay introduced because of the processing of the audio. There are 9 different levels of FLAC compression levels that start from 0 to 8. The higher the level, the higher the compression ratio but it comes with slower encoding speed. Decoding speed on the other hand is more or less the same for all the levels.
Introduced in it quickly became incredibly popular. Its compact file size allowed for fast distribution on the internet, whose bandwidth was a lot lower at the time.
They are processed and created using an encoder. The bitrate set in the encoder determines the resolution and quality of the music you hear. Often, streaming services only offer music delivery in kbps with paid subscriptions.
Free services can go as low as kbps. At this bitrate, diminished quality is obvious. The main advantage of MP3 is the compact file size, compatibility with digital media players, and good sound quality, as long as you encode at kbps.
