I´m looking for a freelancer that can write a cross-platform class in Object-Pascal, it must be compatible with Delphi 7 to run on Windows and with Lazarus to run on MAC OS X (10.6 or greater). To split the native calls to the two operating systems (Windows and MACOSX), the freelancer must use {$IFDEF Win32} and {$IFDEF darwin}. This class will measure the level of audio in a given audio input device. If the level reaches a configured value an event will be triggered. When submitting your offer please write “wmaudio” on it, so I can see who really has read this text. The methods and functions that I need are: - function GetInputDevicesCount : int; returns an integer with the count of available audio sources (line-in, microphone, and so…); - function GetInputDevicesList : TStringList; returns the name of the input devices; - property ActiveInputDevice: int: here will be the audio input chosen; if this property is set to -1, the audio capture will be disabled; - property AudioTriggerLevel: int; here I can set at what level will be the event triggered; - property OnAudioTrigger: TNotifyEvent; this is the event that will be triggered when current audio level > property AudioTriggerLevel;
