My main goal is to change the volume on one sound card based on the decibel level of the audio on another sound card (both on the same computer). Is it possible to detect the DB level? PS: I am writing this in C# ...
I am trying to load a *.wav file to a byte array using C# 3.0 and .NET 3.5 like this: var fs = File.Open(filedialog.FileName, FileMode.Open,FileAccess.Read); long numBytes = new FileInfo(filedialog.FileName).Length; BinaryReader br = new BinaryReader(fs); byte[] bytes = br.ReadBytes((int)numBytes); From byte[58] and to the end...
Hi there, I built an application that plays both uploaded original mp3 files, and copies that have been converted with FFMPEG. I am finding that in some cases the FFMPEG files have a horrible popping/clicking/screeching sound for a split second at startup (hear below). But when I analyze the file in an audio editor there is nothing ther...

Hi, I'm trying to process my byte array which I got from the sampled sourcedataline (Java Sound API). If I'm multiplying the byte array with a fraction number, I will get noise while playing the stream. Before I'm playing the sound I separate the stereo wav file into his left and right channel. This works fine. But if I want to proce...

Hi all. I've been doing a captcha script lately and was rather successful with it. However I want to create another script that creates a sound which can be used with the captcha. E.g. the captcha script generates A2B1FD - and the sound script must be able to read out A, 2, B, 1, F, D. How do I go about doing this? I know it's somethi...
