microSD Card Compatibility
microSD Card Capacity Range: 4 GB - 2 TB
The Song Meter Micro 2 supports SDHC and SDXC cards. These two formats encompass microSD cards between 4 GB and 2 TB in capacity. We recommend SanDisk® cards as the first choice, but other major brands from a reliable electronics retailer will also work.
Large, online marketplaces that allow third-party sellers may include listings for counterfeit SD cards, which are likely to have misleading specifications and may lead to data loss.
We recommend buying SD cards from a reputable electronics or photography supply retailer.
Language in the Song Meter Configurator app and in this documentation may use the term "SD card" generically. This refers to both the full-size SD card used by the Song Meter Mini family and the microSD card used by the Song Meter Micro family.
The Song Meter Micro 2 only supports the use of microSD cards.
SD Card Speed
Minimum Speed Class: C4 (4 MB/s)
Modern SD cards and microSD cards are designed to handle the output of video cameras, which may be writing over 100 frames of high-resolution video to the card each second. By those standards, the data throughput requirements for audio recording are tiny, even when recording on two channels or at the high sample rates required for recording bats.
SD cards and microSD cards are marked with speed classes that indicate the card's minimum sustained write speed. The minimum speed class required by the Song Meter Micro 2 is C4, meaning a minimum sustained write speed of 4 MB/s.
The Song Meter Micro 2 gains no benefit from faster cards, though backing up files to your computer may be faster.
SD Card Power Consumption
SD Cards and microSD cards can vary significantly in power consumption, even among cards manufactured by the same company and sold under the same product line. These variations can affect the battery life of the Song Meter Micro 2.
As a general trend, SD Cards with lower speed classes tend to draw less power than faster cards.
