Media application need and advice

For our organization we need to build an application that can take a web users (mainly from abroad) voice input via a microphone and record it. From what I understand the way to build such an application is still with Flash. I know that this is all changing fast, I mean it’s changing that Flash is the only option. For us Flash would be a good option (we have experience developing in AS3) but I want to make sure it is currently a viable choice. I know that the things being done through JavaScript with jQuery and other frameworks are amazing. I have searched for other options and did not come up with much. Is Flash still the best way for this? Thanks
