Worked Solution & Example Answer:Eight minutes of sound has been digitally recorded - AQA - GCSE Computer Science - Question 5 - 2021 - Paper 1
Step 1
Explain what effects increasing the sampling rate would have on the recording.
Answer
Increasing the sampling rate in a digital audio recording has the following effects:
-
Increased Audio Quality: A higher sampling rate allows for a more accurate representation of the original sound wave. This results in better audio quality, capturing more detail and frequencies within the sound.
-
Larger File Size: As the sampling rate increases, the number of samples taken per second also increases, resulting in larger file sizes. This can impact storage and bandwidth when recording or streaming audio.
-
Higher Processing Requirements: More data requires more processing power during playback or editing. Higher sampling rates might necessitate adjustments in hardware or software capabilities.
