Maven Bintray distribution in Eclipse is not uploading jar files. Error code 401 (Unauthorized) but only for jar packaging?

Asked 2020-Nov-03 at 15:35

I'm trying to deploy a project to Maven to bintray which is successfully uploads the pom file but returns an Error code 401 when uploading jar files.

I have gone through the bintray tutorial, set my settings.xml up properly, added the correct distributionManagement etc fields to my pom file, made sure the project is not a snapshot etc. but cannot seem to get the uploading of jar files working? I've been trying to figure out what might be going on but with no success.

Details on the stack trace pom.xml, settings.xml and eclipse configuration are below. The entire project can be found on github

Am I missing something obvious here? Any help much appreciated.

The error indicates an access issue based upon the HTTP 401 code message:

Error code 401, Unauthorized

Double check your username and password is correct.

Better yet do not put your password into plaintext and instead use a password hash.

[Android][Kotlin] Implement Bandpass Filter with AudioRecord and write to 16BIT PCM file

Asked 2020-Nov-03 at 03:47

Summary: Using Android's AudioRecord, I am trying to implement a bandpass filter and write the filtered audio to a PCM file.

What I libraries have tried so far: https://github.com/berndporr/iirj/blob/master/src/test/java/uk/me/berndporr/iirj/ButterworthTest.java https://github.com/psambit9791/jDSP/blob/master/src/main/java/com/github/psambit9791/jdsp/filter/Butterworth.java

Results: Both will result in distorted filtered audio output when viewing the filtered PCM file. Current Implementation using jDSP Butterworth bandpass filter. I think i am not converting correctly from ByteArray to Double and vice versa. Below are the main information used for this implementation.

QUESTION

Java alternative for scipy butterworth bandpass filter

Asked 2020-Sep-14 at 23:18

I am trying to bandpass some audio frequencies and I have successfully implemented and have got the correct results from scipy.signal module in python. But my necessity is to do that in java so that I can do some filtering in android.

I tried using berndporr/iirj library in java but it returns the data as it originally was. Here is the code in java using this library. The list is a double array containing the audio samples.

For audio filtering in Android, there is a standard equalizer AudioEffect library that looks usable.

FWIW, Java is a painful language to do signal processing in. If you need something beyond Android's AudioEffects, consider using Android NDK and writing in C++.
