android - Power of two bufferSize -


384 I was searching for a way to record the power of two file sizes, and I found

It works well, but I do not know what this equation means: 

  buffer size = 2 & lt; & Lt; (Int) (log (RECORDER_SAMPLERATE) / log (2) -1);

I am familiar with the transfer signed in Java but I am not getting the same output. It gives a buffer size of 16384 samples. I want to reduce it

For example if you type 2 ^ (log (2048) / log (2)) You can give 2048 samples per buffer if your frame rate is 44100, then you record 464 millisecond == 2048/44100 = 0.0464

This is your Buffer Size , you can have the power of two values ​​directly in your buffer size variable (1024, 2048, 4096, etc.)

c# - Showing a SelectedItem's Property -

So I have enabled a rightclick option for my DataGrid. I want to display the only chosen property but it is not behaving like what I would like it to display my name and additional. Public category Paymentinfo {public int PaymentNo {get; Set; } Public string date {get; Set; } Public Double Pay {get; Set; } Public Double Principle {get; Set; } Public Double Interest {get; Set; } Public Double Balance {Received; Set; }} Private Zero MenuItem_OnClick (Object Sender, RoutedEventArgs e) {MessageBox.Show (AmortGrid.SelectedItem.ToString ()); } I'm trying to apply it without using a View Module! If I place a breakpoint where the messagebox and the recipient place it on selected ITEM, then this property will display the payment. A date-payment-principle-interest-balance is the only value that needs payment. Was hoping that it would be something like this MessageBox.Show (AmortGrid.SelectedItem.PaymentNo.ToString ()); When you call ToString () So you get the class typ
