Frequency and volume from wav files and live audio streams

Click For Summary
SUMMARY

To extract frequency and volume from WAV files and live audio streams, utilizing C++ is essential due to its low-level access to audio data. For volume extraction, resources such as JavaAlmanac provide useful guidance. The discussion emphasizes the necessity of understanding operating system-level programming for frequency analysis, indicating that higher-level languages may not suffice for this task.

PREREQUISITES
  • C++ programming for audio data manipulation
  • Java Native Interface (JNI) for integrating Java with C++
  • Understanding of audio signal processing concepts
  • Familiarity with WAV file format specifications
NEXT STEPS
  • Research C++ libraries for audio processing, such as PortAudio or RtAudio
  • Learn about Fast Fourier Transform (FFT) for frequency analysis
  • Explore JavaAlmanac for volume extraction techniques
  • Investigate data modulation techniques relevant to audio streams
USEFUL FOR

This discussion is beneficial for audio engineers, software developers working with audio applications, and anyone interested in real-time audio processing and analysis.

how can i get frequency and volume from wav files and live oudio streams.

please help me

You'll prob need to refer to C++, or at least use JNI. The volume's not too difficult, try referring to: www.javaalmanac.com for more info on that.

However, like I say, the frequency would require a more OS based language, such as C++.

ok 10x.

i will see this site it's good.

drwarezz. can you help me about data modulation?
