Open Audio VisualizerYour specific task is upload audio and see real-time waveform and frequency visualizations. Open the page, drop your input, get the result — typically under a second.
Your goal is estimate flac file size from wav size and compression ratio. Same approach: paste in, get the result, move on. No account, no upload.
Both tools live in the same category, so the choice depends on the exact subtask. Audio Visualizer focuses on upload audio and see real-time waveform and frequency visualizations; FLAC Size focuses on estimate flac file size from wav size and compression ratio. Try whichever description matches your goal more closely — they're both free.

Absolutely. Many users chain multiple tools together — process a file with one, then feed the result into another. Nothing is uploaded, so chaining is essentially instant.
