Thuật ngữ chúng ta thường nghe trong xử lý âm thanh là tốc độ lấy mẫu (Sampling Rate) và tần số lấy mẫu (Sampling Frequency), đều chỉ chung một thứ. Chúng thường có một số giá trị đặc trưng như 8 kHz, 44.1 kHz và 48 kHz. Vậy tốc độ lấy mẫu của một file audio thực sự ...
A sample rate of 44.1kHz captures 44100 samples per second. A sample rate of 48kHz captures 48000 samples per second… and so on. The number of samples captured per second determines the frequency range that can be captured and reproduced.
20 paź 2023 · In summary, sample rate is the number of audio samples recorded per unit of time and bit depth measures how precisely the samples were encoded. Finally, the bit rate is the amount of bits that are recorded per unit of time.
25 lip 2023 · Sample rate is the quality of a stream of digital audio that determines how often it was measured during the initial stage of analog to digital conversions. It refers to the number of times an audio signal is sampled during the process of converting analog audio into digital information.
2 gru 2021 · The quality of an audio file depends upon the sample rate, bit rate, file format, the method of encoding, and the ability of the encoder to get the important bits right. This post will cover some basic concepts of digital audio and how they affect audio fidelity.
6 gru 2013 · Sample Rate (kHz) geeft het aantal snapshots aan per seconde, en Bit Depth (bit) geeft aan hoe scherp (resolutie) deze snapshots uiteindelijk worden. Dat was hem voor deze keer! We snappen dat het een ingewikkeld onderwep is.
9 sie 2023 · The sample rate plays a crucial role in the overall audio quality of a digital recording or playback. A higher sample rate allows for a more accurate representation of the original sound source, capturing a wider frequency range and preserving more details in the audio waveform.
