There are several apps and software available for recording sleep sounds and patterns, including Audacity. Audacity is a commonly used software for recording and editing audio, offering various features such as normalizing levels, de-noising, noise gating, compressing, EQ, cutting, and reordering. It also provides more granular control over audio editing compared to other tools. Some people prefer using their phones or the Windows default mic app for recording, while others opt for dedicated apps like SnoreLabs, SleepBot, and Dream Voices. Each option has its own advantages and caters to different needs, such as ease of use, advanced editing capabilities, or specific sleep-tracking features.

What You'll Learn
Audacity's advanced features
Audacity is a free and open-source digital audio editor and recording software. It is available for Windows, macOS, Linux, and other Unix-like operating systems. It has been praised by reviewers for its features and ease of use, receiving a 5/5 rating from CNET, which called it "feature-rich and flexible".
Audacity has several advanced features that make it a versatile audio editing and recording tool. Firstly, it supports a wide range of audio file formats, including WAV, AIFF, MP3, Ogg Vorbis, and formats supported by the libsndfile library. It can also import and export proprietary formats such as M4A (AAC) and WMA by downloading the separate FFmpeg library. This makes Audacity useful for converting files between different formats and for digitizing records, tapes, or MiniDiscs.
Another advanced feature of Audacity is its support for various audio plugins and effects. It is compatible with LADSPA, LV2, VST, VST3, Audio Units, Vamp, and Nyquist plugins, allowing for a wide range of audio effects and customizations. Audacity also includes built-in effects such as noise reduction, vocal reduction, and isolation for creating karaoke tracks and isolated vocals.
Audacity also has spectrum analysis capabilities using the Fourier transform algorithm and spectrograms. Additional analysis plugins can be added to enhance this functionality, such as those that check audiobooks for ACX compatibility. Furthermore, Audacity can make precise adjustments to the speed (tempo) of audio while maintaining pitch, which is useful for synchronizing audio with video or achieving a precise running time.
While Audacity has features found in digital audio workstations, it is primarily an audio editor and recorder. Some features commonly found in digital audio workstations, such as MIDI editing, piano rolls, virtual instruments, parameter automation, and channel routing, are not yet implemented in Audacity. However, it does offer the ability to record multiple tracks simultaneously, schedule recordings, and use Timer Record and Punch-in-and-roll recording modes.

Other apps for sleep recording
While Audacity can be used to record streaming audio while you sleep, there are also several apps designed specifically for sleep recording and tracking. These apps can provide insights into your sleep patterns and quality, and some even offer personalised recommendations to help you improve your sleep.
SleepScore is one such app that gives you a daily "SleepScore" based on an analysis of your sleep duration, the time taken to fall asleep, light sleep, deep sleep, REM sleep, and wake time. The premium version, priced at $50 per year or $6 per month, allows you to set goals and provides advice on how to achieve them. It offers strategies such as avoiding heavy meals or reducing screen time before bed.
Pillow is another popular sleep tracking app that works best when used with an Apple Watch. It can track metrics like heart rate, respiration, and blood oxygen levels. Pillow provides easy-to-understand sleep analysis, including a sleep cycle diagram and trends over time. It also includes features like audio recordings, sleep sounds, a nap mode, bedtime reminders, and personalised insights. However, one drawback is that it needs to be manually started each night, and it may pick up sounds from others in the room.
SleepWatch is an app that provides personalised recommendations and tips based on your sleep reports. For example, if you go to bed at different times each night, it will recommend setting a consistent bedtime.
Other sleep recording apps include Sleep Tracker, Calm, and AutoSleep. While Calm does not offer sleep tracking and noise recordings, it can be useful if your primary goal is help with falling asleep. It works best when used nightly and offers membership plans of $69.99 per year or $399.99 for a lifetime subscription.

Using Audacity for post-processing
Audacity is a free sound processor that can be used to post-process sleep recordings. Here are some steps to follow to use Audacity for post-processing:
First, open your sleep recording file in Audacity. If you encounter clipping in your audio, lower the gain slider to prevent it. You can also try normalizing the audio, or use the clip fix tool to fix the clipping.
Next, remove any unwanted clicks and pops in the recording using the click removal tool in Audacity. If there are subtle pops that the click removal tool doesn't catch, you can zoom in, select the specific area, and then cut the audio at that point.
Additionally, you can edit out any silence at the beginning or end of your recording by selecting those portions and applying a fade-in or fade-out effect.
Finally, export your processed recording in your desired format, such as MP3 or FLAC. You can also adjust the quality settings to ensure the best sound quality.
By following these steps, you can use Audacity to effectively post-process your sleep recordings, removing unwanted noises, editing the audio for a smoother listening experience, and exporting it in a convenient format for sharing or further analysis.

Recording raw and editing later
Recording raw audio and editing it later is a common practice for many people. Some people might prefer to record directly with Audacity as it removes the need to switch between software when post-processing. For example, Audacity can be used to remove any sibilance, normalise levels, de-noise, noise gate, compress, EQ, cut and reorder, which some video editing software cannot do. Audacity can also work internally in 32-bit floating-point, which gives it more power than some other apps.
However, some people might prefer to record raw audio and edit it later using other software. For example, some people might prefer to use their phone or the Windows default mic app with a dedicated mic, as the audio quality can be more than acceptable, especially if you are just starting out as a small YouTuber. Additionally, some people might not want to use Audacity because they find it difficult to understand how to use it effectively, as it can be a complex suite of tools.
Ultimately, the decision to record raw or edit later is a matter of personal preference and workflow. Different people have different needs, and the right choice for one person might not be the right choice for another. It is important to consider the specific requirements and constraints of your project and choose the tools that will allow you to achieve your desired outcome in the most efficient and effective way.
