From 46888fae6eb7b1dd386f7af7d101ead99ae61981 Mon Sep 17 00:00:00 2001 From: RubbaBoy Date: Mon, 6 Jul 2020 02:33:28 -0400 Subject: Restructured project, added gradle, JUnit, logger, and more Added Gradle (and removed ant), modernized testing via the JUnit framework, moved standalone examples from the tests directory to a separate module, removed sparsely used Java logger and replaced it with SLF4J. More work could be done, however this is a great start to greatly improving the health of the codebase. --- src/com/jsyn/data/HammingWindow.java | 41 ------------------------------------ 1 file changed, 41 deletions(-) delete mode 100644 src/com/jsyn/data/HammingWindow.java (limited to 'src/com/jsyn/data/HammingWindow.java') diff --git a/src/com/jsyn/data/HammingWindow.java b/src/com/jsyn/data/HammingWindow.java deleted file mode 100644 index d8e1238..0000000 --- a/src/com/jsyn/data/HammingWindow.java +++ /dev/null @@ -1,41 +0,0 @@ -/* - * Copyright 2009 Phil Burk, Mobileer Inc - * - * Licensed under the Apache License, Version 2.0 (the "License"); - * you may not use this file except in compliance with the License. - * You may obtain a copy of the License at - * - * http://www.apache.org/licenses/LICENSE-2.0 - * - * Unless required by applicable law or agreed to in writing, software - * distributed under the License is distributed on an "AS IS" BASIS, - * WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. - * See the License for the specific language governing permissions and - * limitations under the License. - */ - -package com.jsyn.data; - -public class HammingWindow implements SpectralWindow { - private double[] data; - - /** Construct a generalized Hamming Window */ - public HammingWindow(int length, double alpha, double beta) { - data = new double[length]; - double scaler = 2.0 * Math.PI / (length - 1); - for (int i = 0; i < length; i++) { - data[i] = alpha - (beta * (Math.cos(i * scaler))); - } - } - - /** Traditional Hamming Window with alpha = 25/46 and beta = 21/46 */ - public HammingWindow(int length) { - this(length, 25.0 / 46.0, 21.0 / 46.0); - } - - @Override - public double get(int index) { - return data[index]; - } - -} -- cgit v1.2.3
