How do I record live streaming audio?
Live streaming audio refers to audio content that is broadcast in real time over the internet. This could include live concerts, radio shows, podcasts, sports commentary and more. Recording live streaming audio allows you to save and archive the content for listening later. There are a few main reasons why someone may want to record live audio streams:
- To listen back to a show or event that you missed hearing live
- To extract audio clips from a stream for editing or sharing
- To have an offline copy of audio content from a stream
- To archive broadcasts for documentation or media purposes
The most common methods for recording live streaming audio are using a software tool or program on your computer. There are many dedicated applications built specifically for capturing and recording streams. You also may be able to use general audio recording software to capture audio if you can route the stream audio into the program. In addition, there are also hardware tools like digital audio converters that can facilitate recording streams.
Audio Sources
There are many common sources for streaming audio these days, from major music services like Spotify and Apple Music, to internet radio stations, podcasts, and more. Some of the most popular audio streaming platforms include:
Spotify – With over 456 million users, Spotify is the most widely used music streaming service globally. It offers access to over 91 million songs, audiobooks, and podcasts (Business of Apps).
Apple Music – Apple’s music service has over 90 million subscribers, making it the second most popular music streamer after Spotify. It provides access to over 90 million songs, live streams, music videos, and radio stations (Yahoo Finance).
Amazon Music – Amazon Music comes bundled with Amazon Prime and has grown to over 90 million customers. It offers an on-demand streaming catalog of over 90 million songs (CNET).
YouTube Music – As a video streaming platform, YouTube has also become a top source for streaming music with over 80 million subscribers to YouTube Music. It provides official songs, albums, thousands of playlists and artist radio (Yahoo Finance).
Additional major services for streaming music include Tidal, Pandora, SoundCloud, and internet radio stations like iHeartRadio. For spoken audio, top sources include podcasts and audiobooks from platforms like Apple Podcasts, Spotify, and Audible.
Recording Software
There are many software options available for recording streaming audio on both computers and mobile devices. Some of the most popular options include:
Audacity – This open source, cross-platform software is one of the most popular options for recording streaming audio on a computer. It’s completely free and provides advanced audio editing features.
OBS Studio – OBS Studio is another open source streaming software that allows you to capture audio from your desktop. It’s a great option for recording audio during live streams.
For mobile devices, the built-in voice memo apps like Voice Memos on iPhone or Sound Recorder on Android can be used to record streaming audio playing on your phone. There are also dedicated streaming audio recorder apps like Audio Recorder for iOS.
Most of these software options allow you to record audio directly from your desktop or phone audio output. They provide configurable settings like sample rate, channel count, and encoding quality.
Recording Hardware
For recording live streaming audio, you’ll need dedicated external recording hardware like an audio interface or mixer to capture the audio source cleanly and route it into your recording software. Some popular hardware options include:
Audio interfaces like the AUDIO4c from iConnectivity are designed specifically for streaming applications. They allow you to connect microphones, instruments, and other audio sources and mix the signals before sending them to your computer. The AUDIO4c has features like loopback recording and zero-latency monitoring to make streaming easier.
Small format mixers like the Yamaha MG10XU are another option for combining multiple audio sources and adjusting levels before routing to your computer. They’re more flexible than basic audio interfaces.
For professional-grade studios, brands like Epiphan offer all-in-one encoding and recording systems with HDMI, SDI, and analog audio inputs designed for live production.
The right audio interface or mixer provides the inputs and outputs needed, good A/D converters, and driver support for streaming software like OBS or XSplit. This ensures you capture high-quality audio without latency or sync issues.
Recording Settings
The key settings to adjust for recording high-quality audio are the sample rate, bit depth, and audio codec. The sample rate determines how many times per second your audio is sampled or digitized. For music, a sample rate of 44.1 kHz or 48 kHz is recommended. Higher sample rates like 96 kHz are best for high-fidelity recordings. The bit depth determines the dynamic range and amount of data captured for each sample. 16-bit is standard, while 24-bit captures a larger dynamic range. For the codec, lossless formats like WAV and FLAC are best to avoid compression artifacts. Lossy formats like MP3 and AAC will save disk space but lose some quality.
Some other important recording settings to consider are the recording mode (mono, stereo, or surround), enabling monitoring so you can hear yourself while recording, and setting the proper gain levels so your audio is free of clipping and distortion. You may also want to add compression, noise gates, and EQ during recording for processing the audio. Just be careful not to overprocess at this stage. It’s generally better to leave most processing until the post-production and mixing phase.
According to digital audio experts, the best OBS settings for recording high-quality audio are a 48 kHz sample rate, 16 or 24-bit depth, and an uncompressed WAV or FLAC codec (Source 1). This captures a full spectrum frequency response while minimizing data loss. As the article suggests, you can always export to MP3 later for smaller files. Just be sure to record initially in an uncompressed format.
Other recommendations are to record in mono or stereo based on your source, enable monitor off to avoid latency and echoes, set your mic gain correctly to avoid clipping, and add noise suppression, compressor, and EQ filters lightly during recording if needed (Source 2). Following these best practices will help you record clean, professional audio with OBS.
Recording from Different Sources
There are specific considerations when recording audio from different online sources like music apps, radio stations, podcasts, video games, etc. Here are some tips for recording from popular sources:
For music/radio apps like Spotify, Pandora, iTunes, etc. you’ll need to record your computer’s internal “Stereo Mix” or “What U Hear” audio output. First enable this in your sound control panel, then select it as the input source in your recording software. See this guide for detailed steps.
To record online radio, open the station in your browser and follow the same steps, selecting “Stereo Mix” as your input. Some stations may not allow recording due to copyright. Consider supporting public radio stations by purchasing recordings directly from them.
For podcasts, while you can record the audio using “Stereo Mix”, it’s better to download the podcast file directly if available. That way you get the highest quality rather than re-recording a streamed version.
Recording from video games requires special software like OBS Studio to capture the game’s audio directly. You’ll also need to adjust OBS settings to record the audio along with game video.
The key for any source is ensuring your computer’s audio output is configured properly in the sound control panel, and selecting “Stereo Mix” as the input in your recording software.
Live vs Recorded Streams
There are some key differences when it comes to recording live streams versus archived streams. With a live stream, you need to record it in real-time as it is broadcasting. This requires having the proper recording software setup ahead of time and actively recording during the live broadcast. According to [1], live streaming tools like OBS Studio allow you to capture your live stream as you are streaming it.
In contrast, archived streams refer to videos that were previously live but are now stored as video on demand (VOD). You can record these after the fact since they are available for playback anytime. When recording an archived stream, you can simply use screen recording software to capture the playback [2]. The main advantage of recording archived streams is you can record them on your own timeline versus having to do it live.
A potential downside of recording live streams is you only have one chance to capture it. If there are any disruptions during the recording, you may miss content. However, recording archived streams allows you to re-record if needed. Overall, the process is simpler for archived streams but requires the stream to be stored as VOD first.

Troubleshooting
Recording live streaming audio can present some challenges. Here are some common problems and potential solutions when trying to capture audio from a live stream:
Audio cutting out – This is often due to internet connectivity issues, either on your end or the stream provider’s end. Try restarting your router and modem or switching to a wired ethernet connection if possible. You may also need to lower the recording quality or bitrate in your recording software settings.
Poor sound quality – Make sure you are capturing from the correct audio source in your recording software. Select the speakers or sound card output rather than the microphone input. You can also try tweaking the audio settings, like increasing the sample rate in the recording software. Some programs like Audacity allow you to improve audio quality after recording (1).
No sound captured – Double check that your speakers or headphones are connected and turned up. Go into your operating system’s sound control panel and confirm the correct input is selected. You may need to enable stereo mix or “what you hear” to record computer audio. Restarting your computer can help too.
Distorted sound – Try lowering the gain/volume in your recording software settings. Boosting the volume too high while recording can cause clipping and distortion. Positioning the microphone further from speakers can help prevent distortion too.
Unable to record audio – Certain DRM protections can prevent recording streamed audio. You may need to use software like Audacity that can capture computer audio directly rather than recording from speakers (2). Modifying Windows settings to allow app recording could help too (3).
Legal Considerations
When live streaming audio, it is important to be aware of any legal issues around recording and distributing copyrighted content without permission. According to this StackExchange discussion, time-shifting audio streams for personal use is generally considered fair use under copyright law. However, uploading recorded streams to other sites or sharing them publicly without permission could violate copyright.
It is also important to know the laws regarding recording conversations without consent. According to this overview, in most states it is illegal to record private conversations without permission from all parties. However, the laws vary by state. Public conversations or streams may be treated differently, but caution should still be exercised.
When live streaming audio that contains copyrighted music or other content, it is best to obtain the proper licenses to avoid any issues. Alternatively, you can stream original or royalty-free content. Overall, be sure to respect copyrights and recording consent laws to avoid legal problems when live streaming audio.
Conclusion
In summary, recording live streaming audio requires audio sources like microphones or system audio, recording software like OBS or Audacity, and often additional hardware like audio interfaces. Configure your recording settings carefully to capture high quality audio without clipping or distortion. Test recording from different sources to ensure your audio comes through clearly. While recording live streams offers flexibility, recording high quality audio for later broadcast has benefits too. Troubleshoot issues by checking connections, software settings, and audio levels at each part of the chain. Be mindful of copyrights, licenses, and other legal considerations when rebroadcasting live audio. With the right setup and knowledge, you can create professional recordings of live streaming audio.
To recap, identify your audio sources and equipment needs first. Select recording software suited for streaming, and optimize settings for the best audio quality. Monitor levels carefully as you test and record. Seek the proper permissions if rebroadcasting others’ streams. Address any troubleshooting issues piece by piece. With practice and care, you can achieve flawless live stream recordings.
