 Supported protocols and formats Top
The following transport protocols are used to manage the high-level exchange of data when streaming audio-based content:
  • HTTP
  • MMS
  • RTSP

    iRadioNet can play and record the following available on-line stream file types (formats):
  • MP3 audio file mp3
  • Windows Media Audio file wma
  • Windows Media file asf

    Moreover, iRadioNet can play the following available local audio formats:
  • Audio file mp2/mp1/wav/cda/ogg/mod
  • MP3 audio file mp3
  • Windows Media Audio file wma
  • Windows Media file asf

    NB.  Please be aware that:
    • To play Windows Media/Audio stream you must have either Windows Media Player or
      Windows Media Format module (3.9 Mb)
      installed on your PC.
  •  Overview of recording functionality Top
    iRadioNet supports recording for main stream formats - direct mp3 and encoded Windows Media/Audio - depending on stream format provided by on-line stations.

    For direct mp3, the stream will be saved as mp3 file without any encoding and transformation and will have the same bitrate as the source.
    For Windows Media/Audio, the source stream will be encoded to mp3 format firstly and then will be saved. In this case bitrate of the file depends on selected recording quality option in the Options Dialog.

    There are two modes of recording - Meta and Non-Meta - for direct mp3 stream.
    If iRadioNet is in the meta mode it can record and save the whole song even if you start recording in the middle of the song.
    In the non-meta mode the application will start recording exactly after pressing the Record button and stop it when you press the button again.

    NB.  Please be aware that:
    • Record service is restricted for unregistered copy:
      only 2 records per the application launching in meta mode or 10 minutes in non-meta.
    • Record service is available only for on-line music. It is desabled if you are playing a music file from a local hard drive or CD-ROM
    • Record service will be switched off and the recorded file will be saved automatically if you change an on-line station or close the application
    • In the meta mode record service will be switched off and the recorded file will be saved automatically if the selected on-line song is ended up
    • Unfortunately not all on-line radio stations provide correct meta data during broadcasting. In this case meta mode for record service is not available.
    • If a radio station can support the meta mode iRadioNet places the "M" indicator opposite the station name on the main screen.
    • If a radio station provides music in Windows Media/Audio format iRadioNet places the "E" indicator opposite the station name on the main screen.

     Options Dialog Top
    Source List Info section allows you to change different files with music source list (see below).

    In Source List Info section you can
  • change the time-out parameter for connection with an on-line radio station
       (recomended to increase it if you have time-out error message);
  • increase/decrease the size of playing buffer;
  • change the timer interval for scan control (see below);
  • switch on/off displaying hints for basic buttons;

    Record Info section allows you to
  • switch the program in meta or non-meta recording mode (see above);
  • enable/disable continious recording - if you set this option on
       the program will continue to record the next song after finishing
       the previous one (only in meta mode);
  • change the folder where to keep recorded files;
  • change the default name for recorded files (for non-meta mode);
  • set the option to add the date sub-folder to save path;
  • switch on/off deleting existed file with the same name before saving
       the new one;
  • run Wizard to congigure recordable input device;
  • set recording options and level;

    NB.  Please be aware that:
    • iRadioNet uses non-standard hints.
      If some button hint is popup up you should wait until it disappears and only then you will be able to press this button.
    • File Num field is used to make default file name different for recorded files in non-meta mode. Its value will be increased automatically after saving the current file.

  •   Recording options Top
    iRadioNet applies encoding to transform the digital audio data into a highly compressed form called bitstream. The result is not the same file as the source, but it will sound the same - more or less, depending on how much compression had been performed on it - the lower the compression ratio achieved, the better the sound quality will be in the end.
    Because compression ratio is a somewhat unwieldy measure, experts use the term bitrate when speaking of the strength of compression. Bitrate denotes the average number of bits that one second of audio data will take up in your compressed bitstream. Usually the units used will be kbps, which is kbits/sec.

    iRadioNet uses two main encoding modes:
  • Constant Bitrate, in which the fixed bitrate will be the same for the whole
       file, so the quality of your mp3 is variable;
  • Variable Bitrate, in which the encoder tries to maintain the given quality
       in the whole file by choosing the optimal number of bits to spend for each
       part of your music. The resulting bitrate range is variable according
       to music complexity, but the quality of your mp3 is smooth.

    Recording options allows you to choose several possible quality encoding modes:
  • User Defined is the default encoding mode with constant bitrate you can
       set yourself.
  • Medium is variable bitrate which provides good transparency to most
       people on most music. The bitrate should be in the 150-180 kbps range.
  • Standard is variable bitrate which is generally transparent to most people
       on most music and is already quite high in quality. The bitrate should be
       in the 170-210 kbps range.
  • Fast Standard is like Standard mode, but this forces the encoder to use
       a faster encoding mode with a lower quality. The bitrate should be
       in the 160-200 kbps range.
  • Extreme is variable bitrate which provides slightly higher quality than
       the Standard mode. The bitrate should be in the 200-240 kbps range.
  • Fast Extreme forces encoder to use a faster encoding mode with a little
       bit lower quality The bitrate should be in the 190-230 kbps range.

    NB.  Please be aware that:
    • iRadioNet cannot improve quality of source stream.
      If an on-line station broadcasts music stream with, i.e., 32 kbps bitrate, setting Record Quality in the Extreme mode will not forse the encoder to provide higher quality for your resulting mp3. iRadioNet uses third-part freeware Lame MP3 Encoder.

  •   How to record on-line music Top
    Click on the Record button while you are listening to on-line music to start recording and click on the button again to stop service and save the recorded file on a hard disc.
    If an on-line radio station provides a title for this song, the saved music file will have the same name.
    If a station does not provide this information, the music file will have a default name. You can set the default name as well as the path where to keep saved files in the Options Dialog.

      How to start with parameters Top
    Put in command line the path to iRadioNet executable file and set of parameters separated by spaces.

    Following parameters are accepted:
  • -v0 .. -v10 Ц set volume level to 0..10
  • -c1 .. Цc5 Ц play the fixed channel 1..5
  • -s# Ц play the station #
  • -r0/-r1 Ц switch off/on record mode
  • -t# Ц switch off recording after # minutes (if -r1)
  • -n# Ц record and save # files (if -r1)
  • -f"path" Ц save recorded files into "path" folder (if -r1)
  • -d# Ц switch off recording when size of the destination directory
       will be more than # MB (if -r1)
  • -e0 Ц close the program after recording (if -r1))

    Sample of parameters to run iRadioNet in Windows Sheduler:
    • "C:\Program Files\iRadioNet\iRadioNet.exe"
                   -r1 -v0 -e0 -s3 -n5 -t45 -d150
    NB.  Please be aware that:
    • Some anti-virus programs not allow you to run the program from Windows Sheduler. You should disable anti-virus protection in this case.
    • Not all on-line stations provide correct data for meta mode (see above). I advise you to set either timer or directory size protection for recording.
    • If iRadioNet is in non-meta mode all transmitted music will be recorded in one file.
    • Record service is restricted for unregistered copy
