  1. Thank You for work!
    Please make ability to launch several copy of app simultaneously. (Like,, just like other apps). This is very needed feature! Thank You!

    What is “Audiojingle”? Etrecheck found it to be suspicious but probably harmless. I uninstalled Ladiocast and trashed the driver to get rid of it. Should I be worried about it. I don’t like how it shows up in my Sound pane in System Preferences.

  3. Is there a diagnostic mode? The station I broadcast at changed (updated?) it’s Shoutcast server, and Ladiocast no longer successfully connects. Server has same auth / audio setup as previous to upgrade. And BUTT works with all the same settings as Ladiocast. Is there a “status window” or something that allows me to watch the handshake, look at failures, etc?

    FLAC encoding request:
    I hope you will consider adding the option of Ogg FLAC encoding.

    “streamy68″ requested this on 2018-07-28. You responded on 2018-07-29 that PCM was a better option because FLAC is not truly lossless. Respectfully, I believe you are mistaken. FLAC is truly lossless, meaning that FLAC encoding followed by FLAC decoding produces audio that is bit-for-bit identical to the original.

    There are 3 reasons Ogg FLAC would be much more helpful than Ogg PCM:
    (1) The official Xiph wiki says the Ogg PCM format “is at best incomplete and at worst completely broken.” Consequently, I do not know any music player that decodes Ogg PCM.
    (2) FLAC is becoming the universal standard for lossless music streaming, now employed by Tidal, Qobuz, Deezer, and YouTube Premium. Also, *all* online music stores that sell lossless downloads offer FLAC format, but almost none offer ALAC. Even Apple does not sell music in ALAC format!
    (3) PCM and FLAC are both bit-perfect (lossless), but FLAC uses less than half the bandwidth.

    (Incidentally, on 2018-08-01, Mr. Shablovsky correctly describes AAC as a very popular lossy format, but erroneously equates this with lossless ALAC. In fact, Wikipedia explains that AAC and ALAC are completely unrelated to each other. The popularity of *lossy* AAC does not recommend ALAC as the best *lossless* format, per paragraph (2) above.)

    Thanks very much for your consideration!

      Hi Bob,
      Thank you for your enthusiastic comment.

      I understood, when people saying flac is lossless, they are talking about its encoding functionality, but not its acceptable source resolution;

      Wiki – FLAC
      “Source encoder
      FLAC supports only fixed-point samples, not floating-point. It can handle any PCM bit resolution from 4 to 24 bits per sample,”.

      Ladiocast’s internal audio is in float 32bit resolution, much more information than that.
      That is why even flac was lossy (and oggpcm not) for ladiocast.
      Though oggpcm was far from best and ladiocast even broke the documented specification, better to show the app’s design policy towards the future versatile and high quality live audio streaming in high speed internet era.

      The design may change depending on good motivation unknown.
      I hope that is helpful.

    Hi! I want to broadcast with Ogg Opus format, but the application always says that “System sample rate in the preferences must be 48000 in using Ogg Opus format”, and all my audio devices are with the 48000 sample rate, what happens? I have macOS High Sierra.

  6. I need to be able to insert my metadata from my layout server (radio automation) do you support this? I can send you the details of how I do it now. Send text to UDP port 4444 then their is a script to extract the Artist and title and add to the stream.

  7. kawauso

    Hi Ian,
    Thank you for your comment on ladiocast.
    About the metadata, ladiocast recommends you to make a daemon program which gets the song info from the server and sets it to ladiocast with AppleScript like;

    tell application “LadioCast” to set metadata song to theSongInfo

    only when updated.
    I hope it’s helpful.

    • kawauso

      Hi Abner,
      Thank you for your interest in ladiocast.
      Recording facility has been requested but unfortunately not yet.

  8. Dennis

    I don’t know what i’m doing wrong. I have an internal rtmp-server at rtmp:// with streamkey ByuPtvF64. I can connect with OBS, but not with Ladiocast. I have two fields in the RTMP-settings (URL and Stream). What do I have to fill in? I tried so much options.

    In OBS you have also two fields in the settings (Server and Stream Key).
    When I use
    Server: rtmp://
    Stream Key: ByuPtvF64

    Then it simply works in OBS. But not in Ladiocast. Why?

    • kawauso

      Hello Dennis,
      Thank you for your report about RTMP. There would be so many factors that make the difference. The rtmp-server name would be helpful.

  9. Rousso

    Hello there, I have got to say spot on job with LC.

    Is there a chance of implementing a reconnect feature? I have on a couple of occasions found that my stream has disconnected and this is due to the Wifi environment (Hard wired coming soon when I have built the home studio). As Im running an automated station at the moment and not sat in front of my Mac 24/7 to reconnect it means Im struggling to keep listeners.

    Having it reconnect or attempt again and again until it reconnects would be a cool feature. I’d even pay for it.

    Many Thanks.


    • kawauso

      Hi Rousso,
      Thank you for the comment. About reconnecting, LadioCast has been intended to use “Event Handler AppleScript”, which you could see in the Events tab of streamer windows. You might need to search to know how to write the scripts especially if you couldn’t show the Help > ReadMe of the App (that seems to happen in some environment).

    For input options I get only ‘N/A’, and ‘Mackbook Pro Microphone’. Shouldn’t I have other input options so I can stream music from say iTunes?

  11. Joseph Pita Lamboy

    Support using Pioneers DDJ-SX3 ladio cast app recognize the interface but no sound or signal thought LadioCast with Serato

      • Joseph Pita Lamboy

        When I connect the new Pioneer DDJ-SX3 and Pioneer DDj-1000SRT the app Ladio Cast in the MacBook Pro recognize the computer sound card input and output signal. When I tried to change the soundcard to the DDJ-SX3 or ddj-1000srt, the app give the option to use one of these sound cards but when I put music I don’t received input and output signal.

        • kawauso

          First of all, check the output channels of your DJ devices match the ladiocast input channels, which are selectable as the most left numbers in the ladiocast’s mixer window panes.
          Good luck.

  12. hank You for work!
    Please make ability to launch several copy of app simultaneously. (Like,, just like other apps). This is very needed feature! Thank You!

  13. Gabriele

    Hi, is there an option to save the streaming to a local file? This is very useful to keep an archive of the live transmission!
    Thank you :) Gabriele

    • kawauso

      Hi Gabriele,
      Thank you for your interest in ladiocast.
      > is there an option to save the streaming to a local file?
      Currently no. Waiting for some revelation.

    • kawauso

      Hello Craig,
      Ladiocast re-tries to connect once when disconnected, if that also fails, error dialog popped up.
      If that the case you suffer, improve your network environment.

      • I switched the Ethernet connection and ran it directly to the router is that goes out, it still disconnected again in the middle of the night after about 45 hours of streaming. We are using the latest version of Ladiocast.

  14. Fantastic Job Kawauso!! I use Ladiocast in conjunction with Soundflower to buss in several audio sources for live video streaming, with OBS handling video duties. Thank you for this app, I honestly don’t know how I’d achieve this otherwise..
    However I was disappointed to discover the file: save/save as/open commands do not include the mixer configuration in the file, as I use different configurations depending on the task in hand.
    Am I missing something in my opening of the .plist file that remembers the configuration?
    No criticism intended, your work is much appreciated…

  15. I want to use Ladiocast with Mac OS X 10.10. (Yosemite) When I download it says I must upgrade to 10.12. Is there a legacy installer to use with OS X 10.10? Thank you!

  16. kawauso

    Hi Rod,
    For the simplicity, older versions are not provided unless you have downloaded them.
    Sorry for the late response.
    Have a good time.

  17. fiona

    I have followed a number of different videos and this still is not working for me, I want to broadcast from my Mac to radio co, I have an external USB Mic and a mixer and LadioCast is not picking up either of them!!

      • fiona

        Its like as if the input levels are switched on or off when they are not, Ladiocast does not seem to pick up any audio from the Mac at all.

        • kawauso

          If you select mac built-in input device (usually microphone), you must see its level as same in mac system preference (sound, check also security & privacy > microphone).

  18. Fada

    We are using RadioKing and We have a huge problem. We’ve attempted to configure Ladiocast. with our studio set up to DJ live using Pioneer S9 Mixer/Serato DJ. The program will find the hardware on our Mac and show levels when “internal mic” is selected, but will not actually allow audio to transmit out when we select the S9 mixer as the input. Can you help us with this issue?

    • kawauso

      Hi Fada,
      > when we select the S9 mixer as the input.
      Check the input channels which are showed and selectable at the most left part of the lasiocast mixer window.

  19. Nidal

    Hi Kawauso,
    Thank you for creating LadioCast (I like the name btw and your sense of humor). Is there any kind of manual for this app? The answer I am looking for is: Does LadioCast override the default settings of MacOS, so that I don’t have to worry about them? If not, how should these settings be?
    Best regards, Nidal

  20. Nidal

    Thank you for the prompt answer!
    Could there be a conflict if the settings are contradictory (different default audio setting on MacOS and LadioCast)?

    the download link for your app LadioCast on the App store for mac is not working. please have it fixed i really would like to use your software thank you

    • kawauso

      micah moses,
      Thank you for being interested in ladiocast.
      So far the app store connect for developers doesn’t show any illegal state for the app.
      Contact your local app store help desk.

    Hi, thank you for Ladiocast! You say, it supports SSL. I can get streaming to work to a non SSL enabled port, but I can’t get it to work on an SSL enabled port. Could you please advise me what to do? By the way: Is Ladiocast still actively developed? Is there a way to support its development?

    • kawauso

      > SSL enabled port
      See errors on server side and client side (

      > Is Ladiocast still actively developed?
      I think yes.

      > Is there a way to support its development?
      Currently none.

      • Lorenz

        Hi, streaming to an SSL enabled port works without any problems with butt. With Ladiocast, I can only get it to work to a port that doesn’t have SSL enabled.

        This is the error popup when trying to stream to the SSL enabled port on my Icecast server:

        Failed to login. Check the network environment or the connection configuration.

        These are the three error messages on Console.App: (I have selected „Icecast“, not „SHOUTcast“; don’t know if it just always says „ShoutStreamer“.)

        ERROR[LCShoutStreamer.m 184] shout_open() = -3, No error

        ERROR[LCStreamer.m 131] NSException = Failed to login.

        ERROR[StreamerWindowController.m 443] NSException = Failed to login.

        Before thinking that I have just misspelled the password or somehow messed up my network configuration, please keep in mind that exactly the same setting works when used on a non-SSL port and it works on the same port using butt with the SSL option ticked.

        Does this error give you a clue as to what might be going wrong?

        • Lorenz

          Sorry, I should have also added that the Icecast2 error.log reports:

          INFO connection/_handle_source_request Source (/stream) attempted to login with invalid or missing password

          • kawauso

            > This is the error popup when trying to stream to the SSL enabled port on my Icecast server:
            Try to make ssl connection to a formally ssl supported public host and see what happens then.

  24. Prince

    Hi Kawauso,

    Thanks for LAdioCast is a pretty cool tool!

    I don’t seem to be able to stream the album art.. perhaps I am doing something wrong?

  25. I just want to say THANK YOU for Ladiocast. For years it has been my preference (over BUTT), and it stays my preferred tool.

    Will you be releasing an M1-ready version? I may upgrade my laptop to an M1 machine soon.

  26. Hi,

    Thanks for your (black box) work., I can see a good will from your side, I miss lot of ore. Sry to say that. To be honest, my nerves are quite overdriven. I am sorry, but you have messed kind of all things up you have to keep in mind, if you start building for the community. The problem is, nobody can support you. Nobody knows and It takes lot of more time and effort to come up with solutions. It is just making me tired in general:

    Would you please consider to make a code repostiory with this e.g Gihub? Don´t you see the problem? It is getting out of control here, I lost now 2hours without any useful information gain. Sry, now you are wasting poeple time, not saving. Now motivation is zero at my side. Thanks!

    By the way your App is just not working and I see no way to get why? I see no living example. I kindly ask why are you forcing us to suffer. Bro, I start my own project if that here is kind of time freezed movement. sry bout hard words,

  27. Remy Garcia


    I have been using Ladiocast for 6 months as an online broadcast for our radio station. Today, ladiocast has been disconnecting from our shoutcast server every 1/2 hour for no apparent reason. I restarted the computer, deleted and redownloaded the software, and checked the ethernet connection, but still get kicked off.


    • kawauso

      Hello Remy Garcia,
      > but still get kicked off.
      See system.log in for what ladiocast saying at that time.

  28. Tadahisa Sugisaki

    Audio MIDI設定の複数出力装置の設定で似たようなことはできるのですが、やはりLadioCastのような柔軟性はありません。Rosseta 2で動いてはいるのですが、仮想サウンドドライバのBlackHoleも対応しましたし、LadioCastのApple Silicon対応を切に願います。

    • kawauso

      Tadahisa Sugisakiさんこんにちは
      情報とご要望大変ありがとうございます。Apple Silicon対応は第一課題でしょうね。

  29. こげぱんっつ


    現在M1 MacbookAirで使わせてもらっているのですが、入力1にキャプチャデバイス(ゲーム音)、入力2にオーディオインターフェース(マイク音)、出力をまとめて同じくオーディオインターフェース(ヘッドホン)としている状態で、以下のような現象が起きます。



    • kawauso

      なかなか答えるのが難しい問題ですね。システムと音声デバイスとの接続が不安定な感はありますので、安定した接続設定を確立することが必要かなと思います(Audio MIDI設定.appで使用する音声デバイスのサンプリングレートを揃えたりLadioCastの設定のサンプルレートを変更したりなど)。
