Safe audio CD ripping technology is an extraction of tracks from audio CDs with improved steadiness to errors that can appear for various reasons.May 18, 2024 updated Author: Yuri Korzunov, Audiophile Inventory's developer with 25+ year experience in digital signal processing, author of the articles that make audio easy for beginners What is "Safe ripping" How AuI ConverteR rip CD-audio Frequently Asked Questions Conclusions Watch and share: Safe CD audio rippingBack to topWhat is "Safe ripping"In the article, "safety" means "steadiness to error reading"."Unsafe" ripper programs may have the following kinds of behavior: When errors happen in extracted data, the software doesn't report problems, and/or The software doesn’t try to recover audio data.Safe ripping technology is: Multiple readings of fragments of CD-audio data, Reading of error markers (C2), Analyze of data obtained in points 1 and 2, Attempt to recover damaged data, Displaying of the error report.Some CD rippers provide this algorithm. Including open-source ones.The result can depend on software implementation.Back to topHow AuI ConverteR rip CD-audioIn AuI ConverteR 48x44 CD ripper applied:1. Raw binary reading from CD2. CD builtin error control (C2) Each byte of the raw audio stream is under control.3. Re-reading several times for each fragment of CD's audio data Re-reading may cause different audio data due to optical-mechanical factors. Also, CD reading devices may use built-in cache. AuI ConverteR provides its own special way of reading that try pass by such kind of cache.4. Complex statistical processing of the full volume of information that is extracted from CD It allows detect errors and try to restore original information.After the ripping, AuI ConverteR shows ripping results: - Fatal errors number (what it can't restore), - Probably restored byte number.This algorithm currently works under Mac OS X [Intel and Apple Silicon] and Windows.We suppose, what new algorithm (implemented under Windows and Mac OS X) gives us more possibilities for control under ripping and for releasing new ideas which we have and continue research currently.For testing, both audio CDs, manufactured by third parties, and own-produced test CDs with different degrees of damage are used.Own-produced test CDs have exactly known.

This part is about handling the data in the file itself, such as searching or editing text or reading and editing binary data with the use of a file format specification paper. This article is mainly aimed at archivists with digital preservation needs, and maybe a bit for data forensic beginners. There is also a PDF version of this document available for download, as well as its Markdown source code. Handling text in binary files Searching Text As already mentioned, you'll encounter text phrases inside binary files. If you look at a lossy compressed audio file like MP3 or MP4, it's quite likely to contain descriptive metadata embedded. In order to read embedded metadata, you need to know at which byte offsets to find which data field and how to interpret it. If it's a number, you already know what to do, but if it's text you may find 2 different ways in which its displayed in the text column: Single-Byte encoding: HELLO Multi-Byte encoding (e.g. UTF-8): H.E.L.L.O. Here's a bogus example how these 2 encodings would look in a hex editor: Single- and multi-byte character encoding of "hello" next to each other (separated by a space character "0x20") The dots between the letters in Unicode are not to indicate an abbreviation, or some ASCII-Art: The dots represent non-printable characters.

April 13, 2014, 10:33pm 1 For various reasons, I need to be able create an audio clip from a byte containing ogg/vorbis (desktop) or mp3 (mobile) data.Currently the only viable options I can see are using external decoders (such as NVorbis)… Which seems insane to me.I don’t need to stream the data, it’s a load it all scenario. Encoded playback would be preferred, but i don’t mind if i have to decode to PCM (which is what i’ll have to deal with with NVorbis).Any easier way to do this? If you dont mind caching to disk, this should work for mp3s (I don’t know about oggs) byte[] rawData = byte[]; string tempFile = Application.persistentDataPath + "/bytes.mp3"; System.IO.File.WriteAllBytes(tempFile, rawData); WWW loader = new WWW("file://" + tempFile); yield return loader; if(!System.String.IsNullOrEmpty(loader.error)) Debug.LogError(loader.error); AudioClip s1 = loader.GetAudioClip(false, false, AudioType.MPEG); //or AudioClip s2 = loader.audioClip; iv7 April 17, 2015, 11:57am 3 Way with handmade web server.using UnityEngine;using System.Collections;using System.Net;using System;using System.IO;public class Main : MonoBehaviour {HttpListener _listener;string url = " Start(){ _listener = new HttpListener(); _listener.Prefixes.Add( url ); _listener.Start(); _listener.BeginGetContext(new AsyncCallback(ListenerCallback),_listener); WWW www = new WWW( url ); yield return www; AudioSource AS = GetComponent(); AS.clip = www.GetAudioClip( true, true, AudioType.MPEG ); AS.Play();}private void ListenerCallback(IAsyncResult result){ HttpListener listener = (HttpListener) result.AsyncState; HttpListenerContext context = listener.EndGetContext(result); HttpListenerRequest request = context.Request; HttpListenerResponse response = context.Response; byte[] buffer = File.ReadAllBytes( "1.mp3" ); response.ContentLength64 = buffer.Length; System.IO.Stream output = response.OutputStream; output.Write( buffer, 0, buffer.Length ); output.Close(); //_listener.BeginGetContext(new AsyncCallback(ListenerCallback),_listener); _listener.Close();}}

The third bit indicates the payload is encrypted using the same mechanism as RTMP uses, however this is rarely used due to encrypted transports such as RTMP being used instead. The FLV packet encryption is generally inherited from a MP4 file that is stored on an Adobe Flash Media Server.Packet types enumerated as 1 is a RTMP set packet size.Packet types enumerated from 3 are RTMP bytes read report, RTMP ping, RTMP server bandwidth, RTMP client bandwidth.Packet types enumerated from 8 are Audio payload, Video payload.Packet types enumerated from 15 are RTMP flex stream send, RTMP flex shared object, RTMP flex message, AMF metadata, shared object, RTMP invoke.Packet type enumerated as 24 is an encapsulated flash video.FLV Tag StructureFollowing that, there are three bytes for the Payload Size denoting length of the Payload Data, then four bytes for the Timestamp in milliseconds (with the last byte used to extend the first three bytes), the next 3 bytes for the Stream ID (incremented for multiple streams of the same type), and finally followed by the actual payload data. There is a direct relation between the fields encountered in an FLV Tag and those found in a RTMP packet, as for example the FLV Packet Type field uses the same numeric values as the RTMP Chunk Type field (ex. 0x08 for audio and 0x09 for video).

About HacksbyHacksby = Hack-a-Furby projectHasbro's Furby toy (year 2012 model) uses audio protocol to communicate with othernearby Furbys and with the official 'Furby' applications for iOS and Android.This project is an educational attempt to analyze and re-create the audio protocoland communicate with Furby using computer in a search for some easter eggs orotherwise undocumented features.At its current state, the project includes:Description on the audio protocol (see below)[An incomplete] description of various Furby commandsAn Perl library and scripts that can generate and play WAV fileswith arbitrary commands (to talk to Furby)A script that can decode commands from a provided audio stream(to interpret Furby's responses).DisclaimerThis information is provided for personal educational purposes only.The author does not guarantee the accuracy of this information.By using the provided information, libraries or software, you solely take the risks of damaging your hardware or your ears.See MIT-LICENSE.txt for more information.Audio ProtocolFurby audio protocol uses high-pitch frequencies to encode special commands (commandis an integer number in [0..1023] range). Furby decodes such commands using its built-inmicrophone and may respond to some of them. When an event occurs (Furby pronouncessome phrase or performs an action), he can also emit such a command in addition toan audible sound. This feature is used in the official application 'Translator'mode, when it recognizes what Furby said and provides an instant translation.Each command is divided into two packages with 0.5 sec gap in between.The first package carries the higher 5 bits of the command number, and the second onecarries the lower 5 bits.If you record the responce from Furby or from iOS application and view its spectrum,You will see that each packet looks like this:2 --------##--------------------------------------##----3 ----##----------------------##--##----------##--------X --##--##--##--##--##--##--##--##--##--##--##--##--##--1 --------------------##--------------##----------------0 ------------##--##------##--------------##------------The total length of the packet is 0.5 second. Here X is a central frequency (17500 Hz),and 0, 1, 2 and 3 are the data frequencies. The distance between each adjacent frequencyis approx. 557 Hz.The central frequency carries no data and was likely introduce to aid in packet decoding.The other four frequencies carry data. If one writes down the packet depicted above as a number in thequaternary numeral system using 0, 1, 2, 3 digits after the name of each frequency, he wouldget the following number: 3200 1033 1032 (for clarity, the number is separated into three quadrupletseach representing a byte).The first byte, 3200, if written in the binary form, will look like this: 11 1 00000, where the firsttwo bits are always 11, the second bit will be 0 for the first packet and 1 for the second, andthe remainder 00000 represents the 5 data bits themselves.The second byte, 1033, depends on the data bits and is used as a checksum (original algorithm is unknown).The lib/Furby/Packet.pm file lists all 64 checksums (32 for the first.
