Sending via email

Sending audio files via email is a quick and easy way to transfer audio. However, most email service providers have a limit on how large an attachment can be, typically between 10 MB and 25 MB. This means that for larger audio files, you'll first need to upload the file to a cloud service, such as Google Drive, and then share it from there.

If your audio file is small enough to send via email, you can follow these steps:

  • Open your email app.
  • Create a new message.
  • Add a recipient and subject.
  • Attach your audio file by clicking "Attach" or the paperclip icon.
  • Select the audio file from your files.
  • Click "Send".

Using a cloud service

If your audio file is too large to send directly via email, you can use a cloud service such as Google Drive, OneDrive, Dropbox, WeTransfer, or MASV. Here's an example of how to use Google Drive to send your audio file:

  • Upload your file to Google Drive by dragging and dropping it into the upload field.
  • Once the file has finished uploading, right-click on it and select "Share".
  • Enter the email address of the person you want to share the file with.
  • Alternatively, you can right-click and select "Get Link" to copy the link and paste it into an email.

Using cloud services

Cloud services are a great way to send large audio files. They are especially useful for ongoing projects, as they eliminate the need for transfers and allow teams to collaborate on files instantly from anywhere.

  • MASV: MASV is an accelerated cloud file transfer tool that is ideal for professional musicians, mixers, and producers who need to send large audio files. It has no limits on uploads and can handle audio files up to 15 TB. To use MASV, simply sign up for a free account, drag and drop your file into the upload field, and enter your recipient's email or generate a shareable link.
  • Google Drive: Google Drive is a cloud storage service that allows you to upload and share files. It is integrated with Google Workspace, so it works best if you are sending files to people who also have a Google Workspace account. To send an audio file, simply upload it to your Google Drive, right-click on the file, and select "Share." You can then enter your recipient's email address or generate a shareable link.
  • OneDrive: OneDrive is a file-hosting service operated by Microsoft that is similar to Google Drive but integrates with the Microsoft 365 suite of apps and tools. It offers a free storage option with 5 GB of storage space and paid plans that allow up to 6 TB of storage. To send an audio file using OneDrive, click the "Upload" button at the top of the page, select your audio file, and then add the email addresses of your recipients or copy and send the link via email or a messaging app.
  • Dropbox: Dropbox is a cloud storage service that allows for easy file sharing and storage. It is similar to Google Drive but makes it easy to transfer files to recipients outside of your organization, such as clients or suppliers. Simply upload your audio file to Dropbox, send a link to the file or folder, and recipients can listen to and download the audio file without even needing a Dropbox account.
  • WeTransfer: WeTransfer is a file transfer service that helps you send large files quickly. If your audio file is less than 2 GB, you don't need to create an account. Simply upload your file, enter the recipient's email address, and click "Transfer." With the free plan, transfers expire after seven days.
  • SoundCloud: SoundCloud is a social media platform mainly used by musicians to share their music. The free plan allows you to upload up to 3 hours of audio clips, while the Pro Plan lets you distribute your tracks to streaming platforms.
  • IBroadcast: iBroadcast is a cloud music player that allows you to upload and manage your playlists for free.

When using cloud services to send audio files, it's important to consider the file format and size. Audio files can be large, especially if they have high sample rates, bit depth, multiple channels, and use lossless codecs like WAV or FLAC. To avoid file size limitations, you may need to compress your audio files or use a cloud service with larger storage capacity.

File compression

There are two main types of compression: lossy and lossless. Lossy compression reduces the audio size by eliminating pieces of information, such as parts of the sound wave that humans cannot hear. This type of compression is commonly used for free audio and is suitable for most situations. However, the dropped information cannot be recovered, and while it usually doesn't affect sound quality, it may be noticeable in more complex or nuanced audio. Lossless compression, on the other hand, reduces file size without sacrificing audio quality. This type of compression is better for situations where quality is more important than file size. Lossless files can always be converted to lossy later if needed.

There are several free tools available for compressing sound files. For Windows, right-click on the file, select 'Send to', and then choose 'Compressed (zipped) folder'. For macOS, right-click on the file and click 'Compress'. You can also use online tools such as MP3 Smaller, AConvert, Ogg Vorbis, FreeConvert, OnlineConverter, XConvert, or FileZigZag. These tools allow you to compress files in various formats, including MP3, WAV, M4A, MIDI, and more. Some tools also offer the ability to manage bitrates and sample rates, which can further reduce file size.

When compressing audio files, it's important to consider the codec and bitrate. The codec is the method used to compress the file, and it determines how small the compressed file will be. The bitrate refers to the quality of the audio file, with higher bitrates resulting in better quality but larger file sizes. Bitrates can be constant or variable, and they are measured in kilobytes per second (kbps). For most purposes, bitrates range between 64 and 320 kbps.

Bitrate

When sending a sound file, it is important to understand the concept of bitrate and how it affects the audio quality. Bitrate refers to the amount of data being transferred into audio and is typically measured in kilobits per second (Kbps). A higher bitrate generally indicates better audio quality, as it allows for a higher dynamic range and produces less distorted noise. However, a higher bitrate also results in larger file sizes and requires greater bandwidth.

The choice of bitrate depends on the intended use of the audio file. For example, if the file is intended for streaming, a lower bitrate is preferable to ensure smooth streaming, while a higher bitrate is more suitable for high-end playback or music creation. The standard audio CD bitrate is 1,411 Kbps, while the MP3 format typically ranges from 96 to 320 Kbps. Streaming services like Spotify use bitrates ranging from 96 to 160 Kbps, with 128 Kbps considered suitable for high-end platforms like Spotify and Apple Music.

The sample rate and bit depth also play a crucial role in audio quality. The sample rate refers to the number of times an audio sample is taken per second, typically expressed in kilohertz (kHz). A standard sample rate for digital audio and audio CDs is 44.1 kHz, meaning the audio is sampled 44,100 times per second. Bit depth, on the other hand, measures the number of bits in each sample, with a higher bit depth resulting in higher audio quality and a larger file size.

When producing audio, it is important to consider the listener's experience. While a high bitrate can improve audio fidelity, it may not be fully appreciated if the listener is using mass-market earbuds or headphones, which may not be able to reproduce the full range of frequencies. Additionally, network conditions and the intended use of the audio should be taken into account when selecting the appropriate bitrate.

In summary, understanding bitrate and its relationship with sample rate and bit depth is essential for achieving the desired audio quality and ensuring compatibility with different devices and platforms. The choice of bitrate depends on various factors, including the intended use, delivery method, and listener's equipment, allowing for a more streamlined production and distribution process.

Sample rate

A higher sample rate provides a greater frequency response and better resolution, leading to a more detailed and accurate representation of the original sound source. For instance, when recording string instruments or cymbals, a high sample rate results in cleaner and crisper audio. On the other hand, a lower sample rate can lead to poor audio quality, with some high-frequency details potentially lost.

The impact of sample rate on audio quality is especially noticeable in the higher frequencies. While the human hearing range is generally between 20 Hz and 20 kHz, music may contain frequencies above this range. Higher sample rates can capture these high-frequency details, which are important for producing high-quality audio productions. However, it's worth noting that the impact of extremely high sample rates on perception is debatable, as most consumer audio hardware cannot maintain such high sample rates throughout the sound reproduction process.

Then, two-finger click (Mac) or right-click (PC) the file and select Get Info (Mac) or Properties (PC) to check its size. Most email providers have a size restriction for files. If your file is too large, you can upload it to a cloud service (e.g. Google Drive) and share it from there. Once you've determined that your file can be sent directly, open your email app, create a new message, add a recipient and subject, click Attach or the paperclip, select the audio file, and click Send.

There are several ways to share large audio files. You can compress the file with software such as Audacity, or break it down into separate files and compress them. You can also upload the file to a cloud service and share it from there. Alternatively, you can use a tool such as Avica Remote Desktop, which allows users to share audio files from remote PCs.

First, upload your audio file to iCloud Drive and manually copy the file's URL. Then, open your preferred email service and paste the URL into a new email window. The recipient can click the URL to view the file and save it to their computer.

There are several factors that influence audio file size, including bitrate, sample rate, file format, and channels. Bitrate refers to the amount of information packed into each snapshot of sound, while sample rate refers to the number of pictures taken of the sound per second. To reduce file size, you can lower the bitrate or sample rate, but this may impact the quality of the sound. You can also use lossless or lossy compression to make the file size smaller. Lossless compression keeps the original quality but moderately reduces the file size, while lossy compression shrinks the file more but can affect quality.
