1. What is FPS in Audio Processing?

FPS (Frames Per Second) in audio processing refers to how many audio frames are processed each second. It's determined by dividing the audio sample rate by the number of frames per buffer, affecting real-time audio processing performance.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• Audio Sample Rate — Typically 44100Hz or 48000Hz for phone audio
• Frames Per Buffer — Number of audio frames processed at once

Explanation: Higher FPS means more frequent audio processing but requires more CPU resources. Lower FPS reduces CPU load but may increase latency.

3. Importance of FPS Calculation

Details: Calculating FPS helps optimize audio processing performance on mobile devices, balancing between latency and battery consumption.

4. Using the Calculator

Tips: Enter the audio sample rate in Hz and frames per buffer. Common values are 44100Hz sample rate and 256 frames per buffer for mobile audio processing.

5. Frequently Asked Questions (FAQ)

Q1: What's a good FPS for phone audio processing?
A: Typically 172-344 FPS (44100Hz/256 or 128 frames) provides good balance between latency and performance.

Q2: How does FPS affect audio latency?
A: Higher FPS means lower latency but higher CPU usage. Lower FPS increases latency but reduces CPU load.

Q3: What sample rates do phones typically use?
A: Most phones use 44100Hz or 48000Hz sample rates for audio processing.

Q4: How does buffer size affect FPS?
A: Larger buffers decrease FPS (and CPU load) while increasing latency. Smaller buffers increase FPS (and CPU load) while decreasing latency.

Q5: Can this calculator be used for video FPS?
A: No, this is specifically for audio processing FPS calculation.
