Those amplitudes are represented by ticks on the y-axis. Each sample is then given an amplitude, being assigned by some algorithm.

#Record scratch soundbyte series#

The sound is recorded through a series of samples, running along the x-axis. Now, for example, consider the sound represented in the image. A sample is defined to be the amplitude of a sound at a given time. The encoding, or more commonly known as modulation, of a sound, is simply done through taking a series of samples from a sound and stacking them back to back.

The quality of a Pulse-code modulation is determined through the sampling rate, how many times a second a sample is taken and through the bit depth, which determines the total amount of amplitudes a value may take up. It is the standard form of encoding used by computers and other electronic devices that use music. Pulse-code modulation is a method for digitally storing analog signals or sounds. Pulse-code Modulation See also: wikipedia:Pulse-code modulation wma like normal WMA files and is only distinguishable using another program.

Otherīelow is a list of other common audio formats that are not supported by Scratch:Īpple's lossy audio format, the format of music purchased in iTunes. The default uncompressed audio format on Windows and also playable in most programs, WAV is a higher quality format than MP3, so it uses more storage. However, due to numerous involved patents, some programs, especially open source or independently developed programs, cannot handle MP3 files as the developers do not have the resources to pay the necessary royalties. The most popular audio format, MP3 (also known as MPEG-3) is a lossy format playable on many devices and programs. List of Formats Supported by Scratchīelow is a description of audio formats supported by Scratch: The reason why that is important is that lossy audio file sizes are much lower compared to uncompressed or lossless audio files, so lossy audio can save a lot of space in a Scratch project. A lossy MP3 file at 128kbit/s is about 1/11 the size of the same sound as an uncompressed audio file. These files, in general, take up less space than those with a constant bitrate (CBR).

Some formats also allow for a variable bitrate (VBR), which changes the bitrate as the music is more or less complex (with a limit).

Sound files can also have different bitrates that may change the perceived sound quality, with the highest usually being 320 kb/s (kilobits per second) and the lowest usually used for music being 64 kb/s. These files ignore components of audio that are harder to hear, such as extremely high and low-pitched notes. However, the most common type is a lossy audio file. These may be useful in projects because they have smaller file sizes than uncompressed audio, with the same sound quality. Lossless compressed audio files also sound perfectly, and are stored partially in 'compressed' ways, allowing them to be about half the size of an analogous uncompressed file. They reproduce the audio as clearly as possible, but take up a lot of space (the WAV format can take up around 10MB per minute ), a property that can be disruptive to the development of a Scratch project. Uncompressed audio files can be compared with BMP images.

There are three main types of audio formats: uncompressed, lossless compressed, and lossy. This article or section needs additional citations for verification.
