Is possible to process the audio before playing?

Solar2D General Questions/Discussion
#1

I am an audio software developer and I want to port an ear training software to iOS and Android. I took a look at Corona for its ease of use but I have these questions:

  • Is there a way to process the audio with sample based algorithms (or any other way, actually) or you just can play it?

  • Is there a way to feed the application with sound from anywhere but your app folder (iPod, Google Music, Spotify API…)?
    Thanks in advance. [import]uid: 185650 topic_id: 32190 reply_id: 332190[/import]

hi,
take a look at this:

corona has some (hidden + experimental) audio features that may be helpful for you.

Hi Canupa,

Thanks for the reply but I don’t need pitch actually. The ear training I develop is aimed to Sound Engineers so I need to process the signal with effects (equalization, compression, distortion, reverb…).

Is there a way to process the audio, apart from pitch? [import]uid: 185650 topic_id: 32190 reply_id: 128143[/import]

Yep, I’ve read that but it’s for panning and applying a pitch. [import]uid: 185650 topic_id: 32190 reply_id: 128169[/import]
