REWIND - Tape recorder

Description

This repository contains the source code of a web application that virtualizes an reel-to-reel tape recorder using the Web Audio API. The project also uses web technologies such as: PHP, HTML5, CSS3 and jQuery. This project provides the following features:

• Audio playback: you can play a track simply with the tape recorder interface, you just need to load the tape from the track loader and play it by clicking on the play button;

• Reproduction Control: you can manipulate the reproduction of the tracks with pause, fast forward (ff) and rewind buttons;

• Reset timer: you can set the timer at zero when you want, by clicking on the reset timer button;

• Speed control: you can set the reproduction speed of the tape;

• Equalization control: you could set the equalization profile for the reproduction;

• Track Loader: using the track loader you can manage the tracks of your collection: you can choose the next track to play and the tracks to delete, you can also replace the audio/video file associated to a track with a new audio/video file specified through the upload interface.

• Upload/Download Area: the tape recorder is also equipped with an "Upload/Download Area" in which you can:

  • Import a single track;
  • Download the tracklist in JSON format;
  • Download all the tracks in a single zip file;

• Waveform visualization: during the playback of a track, it is also possible to visualize the waveform of the audio; the waveform equips a header which tells you the position of the current playback;

Installation

All the project files are in the "taperecorder" folder.

It is recommended to use a docker, you can find the DockFile under the docker folder.

To build a docker image, go inside the docker folder.

$cd docker

Build the image by typing

$docker build -t [TAG] .

You need to specify a tag name which identifies the image.

If you want to change the php configuration, you need to edit the php.ini inside the docker folder and rebuild the image.

Usage

Go to the root folder of the project i.e. ~/PATH_TO/rewind_taperecorder/

then run the docker

$ docker run --rm -it -p [PORT]:80 -v $PWD:/var/www/html [TAG]

Then, open the browser at this address:

http://localhost:PORT/taperecorder/taperecorder.php

Where:

• [PORT]: is the port used of the web server you specified.
• [TAG]: is the image tag name you specified before.
