Study Notes
Digital Audio
- The sampling rate in digital audio measures the number of times per second that a sound is measured during the recording process.
- The most popular digital audio format is not specified, but audio files can be played using media player software.
Audio Equipment
- A mixer is a device that contains a variety of input and output jacks, along with audio-processing circuitry.
Image File Formats
- Color depth in an image refers to the number of bits used to represent the color of each pixel.
- Bit-depth is used to control color depth in an image.
- Lossless compression techniques, such as Huffman coding, recode data in an image file so that it contains fewer bits.
Graphics
- Vector graphics contain instructions for drawing shapes and lines.
- Raster graphics editors are used to modify or edit bitmap graphics.
- SVG (Scalable Vector Graphics) is a file format used for vector graphics on the Web.
- Vector graphics usually require less storage space than bitmap images.
Speech Synthesis
- Text-to-speech synthesis is the process by which machines produce sound resembling spoken words.
Compression Techniques
- Lossy compression is a technique commonly used in digital media, which involves discarding some of the data to reduce the file size.
- Rasterization superimposes a grid over a vector image and determines the color for each pixel.
