Detailed music format

classic wave

As the most classic Windows media audio format, the WAVE file is widely used, which uses three parameters to represent sound: the number of sampled bits, the sample rate, and the number of channels.
The channels are divided into mono and stereo, and the sample rates are generally 11025 Hz (11 kHz), 22050 Hz (22 kHz), and 44100 Hz (44 kHz). The capacity occupied by the WAVE file = (sampling frequency × sampling bits × channel) × time/8 (1 byte = 8 bits).

traditional mod

MOD is a wavetable-like music format, but its structure is similar to MIDI, it uses real samples, and the volume is small. In the earlier DOS era, MOD was often used as background music for games. Modern mods can contain many audio tracks in many formats, such as S3M, NST, 669, MTM, XM, IT, XT, and RT.

midi music computer

MIDI is short for Musical Instrument Data Interface. Records the sound played by the instrument digitally (each note is recorded as a number), and then synthesizes these records via FM or wavetable during playback: FM synthesis is the sound of the instrument is simulated by mixing the multi-frequency sounds; wavetable synthesis consists of storing the sound samples of the instrument in the wavetable of the sound card and extracting the sound from the wavetable as you play.

Boss Boss MP3

It can be said that MP3 is famous, it uses MPEG Audio Layer 3 technology to compress the sound with a compression ratio of 1:10 or even 1:12, with a sampling rate of 44kHz and a bit rate of 112kbit/s. .
MP3 music is music stored in digital form. If you want to play it, you must have a corresponding digital playback and decoding system. Generally, MP3 digital music is decoded by special software and then restored to a waveform sound signal for playback output. This type of software is called For MP3 players, such as Winamp, etc.

Overlord RA series online

RA, RAM, and RM are Real’s mature network audio formats, using “streaming audio” technology, making them well suited for network streaming. Information such as copyright, singer, producer, mail and song title can be added during production.
RA can be called the supreme lord of multimedia communication on the Internet. It is suitable for streaming on the Internet and is currently the best format for listening to online music online.

VQF with high compression ratio

VQF or TwinVQ is an audio compression technology developed by Nippon Telegraph and Telephone and Yamaha Corporation.
The audio compression rate of VQF is almost twice that of standard MPEG audio and can reach approximately 1:18 or even higher. And popular compression formats like MP3 and RA are usually only around 1:12. But it still won’t affect the sound quality, when VQF compress music at 44kHz-80kbit/s audio sampling rate, its sound quality will be better than 44kHz-128kbit/s MP3, when compress at 44kHz-96kbit/s , the music is close to 44kHz-256kbit/s MP3.

MD minidisc

MD (ie MiniDisc) is a comprehensive portable music format released by SONY in 1992. The compression algorithm it uses is ATRAC technology (the compression ratio is 1:5). MD is divided into Recordable MD (Recordable, with two heads of magnetic head and laser head) and Single Play MD (Prerecorded, only laser head).
The powerful editing function is the strong point of MD. You can quickly select tracks, move tracks, merge, split, delete and edit track titles. It is more personalized than CD and you can have your own MD album at any time. MD products include MD Walkman, MD bedside audio, MD car audio, MD recording deck, MD camera gun and MD driver, etc.

What audio formats are there? All you need to know

FLAC, WAV, AIFF, DSD … these are just some of the initials that you can find when you are looking for a digital format. They are also accompanied by technical data such as sample rates and bit depth. So many terms can leave you more misplaced than a chicken at a dance. And it is that unless you are an expert in digital sound, the process to choose the audio format that best suits your needs can be a mess. But if they explain it to you, the topic is relatively simple. That is why at Culturasonora we have prepared a complete guide for you on the different audio formats most used. This will prevent any acronym from taking you on the dark side.

What are Bit Depth and Sample Rate?

These two concepts are basic. To understand how audio formats work you need to know what Bit Depth and Sample Rate are. These are two measures that indicate the quality of a digital audio file. We are going to try to summarize it so that you keep the general idea

samplerate

When you read the specifications of the audio formats you come across a couple of figures. For example: 32-bit / 192kHz or 24-bit / 96kHz. These numbers indicate the bit depth and the sample rate. These references tell us how much information the different formats transmit and the quality of the sound. For example, the audio we hear on a regular CD, or on a Spotify stream, is 16bit / 44.1kHz. Samples are always measured in Hertz (or hertz) and bit depth in Bits.

Softwares or hardwares usually do not work with a continuous flow of information, but usually use pieces, samples or samples to effectively manage the data that is transmitted. The sample rate is the number of samples per second that are obtained from a recording. The higher the number of times a device plays samples, the higher the sound quality. Each of these extracts or samples has a certain amount of information, which is the bit depth, or bit depth.

So that you understand it better we are going to make a somewhat beastly analogy, which is not entirely true, but that will help you get the sense of all this. Which is what interests us. If you control a bit of photography and image you will get it right away: the sample rate would be something similar to the frames or frames per second of a video, and the bit rate would be similar to the pixels of a photograph. The higher the bit depth number, the more information each sample will have. The more pixels an image has, the higher resolution each frame of a video will have. The more frames per second a movie has, the better definition. In short: the higher the number of the Bit Depth and the Sample Rate, the higher the quality of the audio file. Heard cooking?

Audio formats: MP3 vs WAV vs AIFF

What is the MP3 format?

If you’re interested in getting some audio fidelity and decent sound from your files, you’ll want to avoid this format. Why? Because basically an MP3 is a file that sacrifices audio quality to minimize size. They weigh very little for any device to read. The negative? Compressing these files provides poor, almost lifeless sound. Today, hardly anyone uses this format seriously. Even its creators recently ended the license by declaring it dead. But surely from time to time you come across a zombie file with this format.

What is WAV format?

WAVs (Waveform Audio File Format) are just as common but better for anyone who wants a decent audio format. They are higher resolution files than MP3s. A WAV is an audio piece that is encoded with something known as Pulse Code Modulation (PCM), a medium that encodes analog audio pieces and converts them to digital so they can have the Sample rate and Bit Depth of the that we have already talked about previously.

What is the AIFF format?

The AIFF (Audio Interchange File Format) audio format is very similar to WAV in that it also uses PCM to encode analog audio pieces and present them in digital format. This format was born as a response from Apple to Microsoft’s WAV, and at the beginning it could only work on MAC computers. Currently AIFF and WAV are more or less interchangeable.
In summary…
To close this topic, we will tell you that if you have a file in WAV or AIFF audio formats, you will hear a piece of sound of good quality. Normally these formats are used in files that we reproduce through our services, such as the iTunes music library. We will not see them in online streaming services, which tend to use special types of files.
