Re: Audio Fluctuation
Sorrie, I got mixed up with my earlier post. The value should be 3kHz @0dBFS level...

Re: Audio Fluctuation
Actually the left is level and the bottom is frequency. However Wavosaur doesn't provides any value on the X & Y axis. But, the value should be at 60Hz @-10dBFS & 7kHz @ -22dBFS. The Sample rate is at 44.1kHz and the Buffer size is 1024. I realised that if I increase the buffer size to 2048, I have ...

Audio Fluctuation
Hi, I did a simple 3KHz mono tone using audacity 1.26 for a duraion of 30sec, I export this as a WAV file (16bit PCM) using 44.1kHz sampling rate. When I playback this wav file using a audio analyzer "Wavosaur" I can see that this audio file is not table. See attached picture for more detail. Is thi...

Re: High Noise Spectrum above 13kHz
Hi, Actually the defualt setting for the sample format was already set at 32 bits float. But you have given me a good ideal to investigate the dithering effect on the waveform. I look up at your website and understood that the shape provide a good listening quality but at the compensation of noise a...

High Noise Spectrum above 13kHz
Hi, I've made a audio track of 60Hz and another audio track at 7kHz. After which I used the mix and render function to mix the two audio signal together. I've got a nice spectrum display up to 13kHz, however if you see the attachement file, the noise level at the spectrum above 13khz is rather hight...
