java - Opus audio File to Wav conversion -


good morning,

i'm trying convert opus audio file wav file on java.

i've been seeking different solutions different libraries, , i've found possible solution. problem output wav audio file has lot of noise, distortion, , don't know how solve this.

here code:

public void opustowav() {      jopusfile infile = new jopusfile(input_file);     audioformat sourceformat = infile.format;     jopusdecodable decoder; // com.glester.jopus.jopusdecodable     bytebuffer samplebuffer;     wavefilewriter wavwriter; // net.sourceforge.jaad.util.wav.wavefilewriter      byte [] buf;     int bytesread = 0;      try {         decoder = jopusbufferfile.loadfromfile(input_file);         samplebuffer = decoder.getsamplebuffer();         wavwriter = new wavefilewriter(outputfile, 44100, sourceformat.getchannels(), sourceformat.getsamplesizeinbits());          buf = new byte[samplebuffer.capacity()];          while(true) {             bytesread = decoder.read();             if(bytesread <= 0) break;             samplebuffer.get(buf);              // needed reduce sample volume in byte array??              wavwriter.write(buf, 0, bytesread);         }          wavwriter.close();         decoder.close();         infile.close();     } catch(urisyntaxexception | ioexception e) {         system.out.println("error decoding opus file --> " +  e.getmessage());     } }

i've tried modify sample volume in output byte array, problem still there.

any idea how solve this?

p.d: have tried concentus library well, no difference.

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m...

python Tkinter Capturing keyboard events save as one single string -

is possible store keyboard events 1 string? code below stores 1 char , prints it. card reader or bar code reader, contains collection of character/ string not 1 character @ time. goal save char pressed text variable. from tkinter import * root = tk() def key(event): text= event.char text+= event.char print ("pressed", text) def callback(event): frame.focus_set() print ("clicked at", event.x, event.y) frame = frame(root, width=100, height=100) frame.bind("<key>", key) frame.bind("<button-1>", callback) frame.pack() root.mainloop() currently, creating text variable , everytime key() function gets called, , text stores last character typed. you can define text module level variable , , use module level text inside key function - text = '' def key(event): global text text+= event.char print("pressed", text)

sql server - Why does Linq-to-SQL add unnecessary COUNT()? -

here tables: create table customer ( cid int primary key, name varchar(32) ) create table ord ( oid int primary key, cid int foreign key references customer, address varchar(20) ) here's linq-to-sql statement: var aaa = c in db.customer select new { c, o = c.ord.tolist() }; and here's inexplicable query generated linq-to-sql: select [t0].[cid] [cid], [t0].[name] [name], [t1].[oid] [oid], [t1].[cid] [cid2], [t1].[address] [address], (select count(*) [dbo].[ord] [t2] [t2].[cid] = [t0].[cid]) [value] [dbo].[customer] [t0] left outer join [dbo].[ord] [t1] on [t1].[cid] = [t0].[cid] order [t0].[cid], [t1].[oid] i want understand how rid of count(*) part. it's entirely uncalled for! linq needs count(*) in order determine number of entries returned o = c.ord.tolist() .
