S
The number of samples per second that are recorded when an audio signal is digitized. It is specified in Hertz (Hz) and determines the audio quality. Typical sampling rates are 44.1 kHz (CD quality) or 96 kHz (Hi-Res audio).
Mechanical vibrations between 16 Hz and 20 kHz, which propagate as a wave and are perceived by our ears as sound.
A measure of the loudness of a sound signal. It is measured in decibels (dB) and indicates how strong the sound pressure is compared to a reference value. A higher sound pressure level means a louder reproduction of the audio signal.
Generation and emission of sound waves by a sound source, such as a loudspeaker. It describes the ability of a device to generate sound and make it audible. The sound emission is often evaluated in relation to the sound quality and volume of an audio device.
Process of converting electrical signals into sound waves and vice versa. This is done with the help of loudspeakers, which convert electrical energy into sound energy, and microphones, which convert sound waves into electrical signals. This sound conversion enables the playback and recording of audio in various devices such as loudspeakers, headphones and recording devices.
A flexible membrane that connects the edge of a loudspeaker to the voice coil. It allows the cone to move and also serves as a seal. The surround influences the sound quality and frequency response of the speaker.
Electrical or digital transmission of audio information, either in analog or digital form.
A signal processor processes audio signals to optimize or modify them and is used in many audio devices and applications to control sound quality and effects.
Spatial arrangement of sound sources in a stereo or surround system that gives the listener the feeling that the sound is coming from different directions.
"Sony/Philips Digital Interface" ist eine Schnittstelle zur elektrischen oder optischen Übertragung von Audiosignalen. Es wird häufig verwendet, um digitale Audiodaten zwischen verschiedenen Geräten wie CD-Playern, DVD-Playern und Verstärkern zu übertragen. SPDIF ermöglicht eine verlustfreie Übertragung von hochwertigem digitalen Audio, über optische oder koaxiale Kabel.
Spotify is a popular music streaming service that allows users to listen to millions of songs and podcasts online, create playlists and stream content on different devices.
Funktion, die es ermöglicht, Musik von der Spotify-App auf verschiedenen Geräten abzuspielen. Dabei greift das Ausgabegerät selbst per WLAN auf den Server zu. Bspw. ein Smartphone dient dann "nur" noch als Fernbedienung zur Steuerung, ist aber selbst nicht mit dem Abspielgerät verbunden. Die Vorteile liegen u. a. in einer besseren Soundqualität und einer stabileren Verbindung.
The reproduction of sounds via two separate channels to create a spatial sound image. Different audio signals are distributed to the left and right speakers to create a wider sound stage. This enables a more realistic and immersive listening experience.
Arrangement of loudspeakers and listening position in a triangle to create a spatial sound image. The speakers are placed in front of the listener in an isosceles triangle. This arrangement enables a realistic reproduction of music and sound effects.
An amplifier that amplifies two channels (left and right) to reproduce stereo sound.
Transmission of music or other audio content via the Internet in real time. The data is played continuously without having to be downloaded first. Users can access a wide range of music tracks and albums and stream them directly via their devices without having to physically own them.
Speaker specially developed for the reproduction of low frequencies. It amplifies and reproduces the bass components in music or sound design. Subwoofers are often used in home theater systems, car audio systems and professional audio systems to produce powerful and precise bass.
The ideal listening area where the sound is at its best. It is the point at which the speaker position and the listening position are optimally matched to achieve a balanced sound reproduction. Away from the sweet spot, the sound can lose clarity and precision.
