Digital Audio - Creating a WAV (RIFF) file Abstract: This tutorial covers the creation of a WAV (RIFF) audio file. It covers bit size, sample rate, channels, data, headers and finalizing the file. This document is designed to cover uncompressed PCM audio files, the most common type of RIFF files. This document does not cover inserting useful data into the WAV (RIFF) audio file. What's a WAV (RIFF) File? A WAV (RIFF) file is a multi-format file that contains a header and data. For the purposes of this document, only a simple PCM file will be explored.
A WAV file contains a header and the raw data, in time format. What's bit size? Bit size determines how much information can be stored in a file. For most of today's purposes, bit size should be 16 bit. Adventus Df Keygen.
8 bit files are smaller (1/2 the size), but have less resolution. Bit size deals with amplitude. In 8 bit recordings, a total of 256 (0 to 255) amplitude levels are available.
In 16 bit, a total of 65,536 (-32768 to 32767) amplitude levels are available. The greater the resolution of the file is, the greater the realistic dynamic range of the file. CD-Audio uses 16 bit samples. What is Sample Rate? Sample rate is the number of samples per second. CD-Audio has a sample rate of 44,100. This means that 1 second of audio has 44,100 samples.
DAT tapes have a sample rate of 48,000. When looking at frequency response, the highest frequency can be considered to be 1/2 of the sample rate. What are Channels? Channels are the number of separate recording elements in the data.
For a real quick example, one channel is mono and two channels are stereo. In this document, both single and dual channel recordings will be discussed. What is the data? The data is the individual samples. An individual sample is the bit size times the number of channels. For example, a monaural (single channel), eight bit recording has an individual sample size of 8 bits.
A monaural sixteen-bit recording has an individual sample size of 16 bits. A stereo sixteen-bit recording has an individual sample size of 32 bits. Samples are placed end-to-end to form the data. So, for example, if you have four samples (s1, s2, s3, s4) then the data would look like: s1s2s3s4. What is the header? The header is the beginning of a WAV (RIFF) file. The header is used to provide specifications on the file type, sample rate, sample size and bit size of the file, as well as its overall length.
