mediarecorder - How to use different audio encoding bitrate for media recorder android -


In my application I am using the media recorder for audio recording. I use different bit rate 32,64,128,160 etc. Want to do 

  recorder = new MediaRecorder (); / ****** Audio source ****** / try {if (audio_source.equals ("camcorder") recorder.setAdosource (MediaRecorder.AudioSource.CAMCORDER); Otherwise if (audio_source.qual ("MIC")) recorder.SetAudio Source (Media Records. AudioSOS.MIC); Other recorders.SetAudio Source (MediaRecorder.AudioSource.DEFAULT); } Hold (exception e) {recorder.setAudioSource (MediaRecorder.AudioSource.MIC); } / ****** Audio channel ****** / try {if (audio_channel.equalsIgnoreCase ("mono")) {recorder.setAudioChannels (1); } And if (audio_channel.equalsIgnoreCase ("stereo")) {recorder.setAudioChannels (2); }} Hold (exception e) {recorder.setAudioChannels (1); } System.out.println ("bitrate -" + bit_rate); If (Build.VERSION.SDK_INT> = 10) {recorder.setAudioSamplingRate (44100); // 44100} and {recorder.setAudioSamplingRate (8000); // 44100} / ****** AudioEncodingBitRate ***** * / Try {System.out.println ("Try ..." + bit_rate); If (bit_rate.equalsIgnoreCase ("32")) {recorder.setAudioEncodingBitRate (32000); } And if (bit_rate.equalsIgnoreCase ("64")) {recorder.setAudioEncodingBitRate (64000); } And if (bit_rate.equalsIgnoreCase ("96")) {recorder.setAudioEncodingBitRate (96000); } And if (bit_rate.equalsIgnoreCase ("128")) {recorder.setAudioEncodingBitRate (128000); } And if (bit_rate.equalsIgnoreCase ("160")) {recorder.setAudioEncodingBitRate (160000); }} Hold (exception e) {recorder.setAudioEncodingBitRate (64); } / ****** file format ****** / /recorder.setOutputFormat (MediaRecorder.OutputFormat.MPEG_4); If (format.equals (".mp4")) {recorder.setOutputFormat (MediaRecorder.OutputFormat.MPEG_4); } Else {recorder.setOutputFormat (MediaRecorder.OutputFormat.THREE_GPP); } If (build.VERSION.SDK_INT> = 10) {recorder.setAudioSamplingRate (44100); // 44100 Recorder .SetAudio Encoder (Media Records. Audio Encoder.ac); } Other {recorder.SetAudio SampleGenet (8000); // 44100 Recorder.SetAudio Encoder (Media Records. Audio Encoder.AMR_NB); } Recorder.setOutputFile (audiofile.getAbsolutePath ()); Recorder.prepare ();   
 But I did not get any changes to quality using all the above bit rate situations. How can I use it?  
  
 
 
 According to the bitrate bits are set per second and  
 
 are ready () Can check additional parameters on the parameter to determine whether a specified bit rate is applied, and sometimes the pass bitrate will be internally clotted so that it can be ensured that depending on the capabilities of audio recording Can move forward smoothly on the stage.   
 I think this clipping has happened in this case, because 160 seconds per second is ridiculous.

Java - Error: no suitable method found for add(int, java.lang.String) -

I'm in the middle of homework work and I'm stuck. At this point in my code, I think that I should have a GUI window that opens and allows me to type "inserted text number". Notice is not going anywhere but at this point, If I pass through the problem then it will be in a linked list. I am getting two of the same error for the lines. Add (index, element); And I can not seem to get past it, there is no suitable method for the error "add (int, java. string string)". Code is below, please advise. To clarify - this will not be a method error because it is a linked list. There should not be any way involved. import java.awt. *; Import java.awt.event. *; Import javax.swing. *; Import java.util. *; Import java.util.Scanner; Import java.util.LinkedList; Public class TopTenList JFrame {Private TopTenList tt; See the Private JTextArea list; Private JTextField cmdTextField; Private JTextField resultsTestfield; // This GUI window is the code for the public toptist...

java - JPA TypedQuery: Parameter value element did not match expected type -

I am using JPA 2.0 and getting the following code in the DAO layer: Public Zero Test () {string key = "status"; String [] Conditions = {"A", "B"}; & Lt; TestTable & gt; Results = Search (Keys, Conditions); } Public listing & lt; TestTable & gt; Search (string key, object value error) {string sql = "test ndf to testlet and jade nand." + Key + "in:" + key; TypedQuery & LT; TestTable & gt; Query = entityManager.createQuery (SQL, TestTable.class); Query.setParameter (key, Arrays.asList (valueArr)) / *** Error Line *** Return query.getResultList (); } In the above error line, it throws the following exception: java.lang.IllegalArgumentException: parameter value element [[Ljava.lang.String; @ cbe5bc] did not match the expected type [java.lang.String] Why is this expected type string while actually this string []? Please help! Note: This is derived from the normal routine and is a simplified code. I can no...

c++ - static template member variable has internal linkage but is not defined -

Yes, I know, there is a question with almost the same title, but it refers to a different situation. Error message) In my case, I have a .cpp file with a big named designation name (implementation details). There is a property class template with a static data member in that name space, which I need to access from outside the unknown namespace. I give it a little bit of meat: file.hpp namespace Bar {template & lt; Typename A & gt; Struct foo {static_assert (is_same & lt; a, float & gt; :: value} is_same & lt; a, double>: value, ""); Fixed zero set_static_var (a const & x); // ...}; } and file.cpp namespace {template & lt; Typename A & gt; Struct foo_traits {// supports the implementation of several static code bars: foo & lt; & Gt; Fixed A data; }; The template's & lt; & Gt; Float foo_traits & lt; Float & gt; :: datum; // No change if this is in the global namespace template & lt; & Gt; Doub...
