Waveforms
- How can I know the size of the arrays in the waveformSize parameter?
- I'm researching how to graph the sound from each mic of the iPhone individually in realtime (there are 3 of them on the device). Can Superpowered help me?
- Should the SuperpoweredWaveform class not be used directly? Should I instead only use the SuperpoweredOfflineAnalyzer to get the waveform data ?
Offline Analyzer
- I’m planning to build an ios app which will need to do some pitch and tempo detection. Which part of Superpowered should I start with?
- I understand that the upper 4 bits are the bass notes 0-11 and that the lower 4 bits are the mid notes 0-11, but I am getting a number. How do I know what are the bass notes are?
- Am I correct in thinking I need to copy the SuperpoweredAnalyzer.h file into my jni folder?
- Can I generate a waveform image with Superpowered? I am thinking about using the offline rendering method's low/mid/highWaveform.
- Is the Analyzer applicable to monophonic tracks only? Or it works for the polyphonic multi tracks as well?
- Is it possible to get analyzed data during offline processing ?
Tips and Ideas
- Are there any resources you can share about how to approach an auto mixer with Superpowered?
- Can I use Superpowered to detect DTMF tones?
- Can I use the offline analyzer for real-time pitch detection?
- Can your tool detect and export more fine-grained pitch data in Hz/msec using MIDI pitch bend messages ?
- Does the Superpowered API do pitch detection based on a monophonic vocal recording in mp3 format or compare and return Hz/msec for each detected pitch?
- I don't know how to return most of the analysis results from Offline Analyzer to my java code so that I can use and display them. Do you have any tips?
FilterBank
- Can I have more than 8 frequencies in frequencies array [8] in a sample project?
- How can I print to console the max frequency (or the max band) every 10 ms or every time the frame updates?
- I am broadcasting a signal at 1900hz.How should I detect it through your API?
- Is there a way to use the audio SDK for chord detection?
BPM
- Can you please provide documentation as to how much the BPM will be changed if we increase tempo from 1 to 2 ?
- Can you tell me more about the BPM Tracking part of the Superpowered analyser? We’re looking into capturing the tempo and phase of ambient audio to sync our metronome to.
- How can I improve BPM detection? I'd like to increase the sample size and/or the amount of song it processes
- The real BPM of my track is 98, however I am getting 198. Or the real BPM is 60 and I get 100. Can you please tell me what the problem might be?
